It is located in the northwest of Arizona, USA. It is formed by the erosion of the Colorado River for millions of years. The cliffs are colorful and steep. 1979 The Grand Canyon is listed as a World Heritage Site. The name of the Grand Canyon appears in many unofficial versions of the list of the seven natural wonders of the world. It is currently managed by the Grand Canyon National Park.
The Grand Canyon is 446 kilometers long, with an average depth of 1.200 meters and a width ranging from 0.5 kilometers to 29 kilometers. When the Colorado Plateau rises, the Colorado River and its tributaries cut the sedimentary rocks, thus forming the Grand Canyon. The history of geological changes in the past 2 billion years is unobstructed.
geographical environment
Seen from the river, the deepest part of the Grand Canyon is about1900m. From Lee Ferry to Hance Rapid, the canyon has a gentle slope and exposed rock strata. From bottom to top, a series of rock series from Precambrian to Cenozoic are exposed along the wall, with clear horizontal levels and different rock tones, which are representative biological fossils in various geological periods. The canyon ends at the Great Walsh Fault.
The north bank of the Grand Canyon is more than 300 meters higher than the south bank, and the Colorado River is closer to the south bank. The precipitation in the northern highland is relatively high, and almost all of its runoff flows into the Grand Canyon. On the other hand, the runoff from the south bank highlands flows away from the canyon along the terrain. This aggravated the erosion of the canyon and widened the canyon and its tributaries on the north bank of the Colorado River more quickly.
Due to the difference in altitude, the temperature on the north bank of the Grand Canyon is relatively lower than that on the south bank. In winter, there is often a lot of snowfall in this area. Looking from the north shore, the expansion of the canyon is more obvious.
The edge of the Grand Canyon is a forest. The farther you go into the canyon, the higher the temperature, and the bottom of the canyon is similar to a desert area. Therefore, the Grand Canyon contains a series of ecological environments from forests to deserts. There are more than 1500 species of plants in the national park, including 355 species of birds, 89 species of mammals, 47 species of reptiles, 9 species of amphibians and 17 species of fish. Theodore, the 26th president of the United States? Roosevelt was also one of the many fans of the Grand Canyon. He hunted pumas many times or enjoyed the scenery here.
Geological change
The details of the formation of the Grand Canyon Sunset Canyon are still controversial. According to geologist Wayne? Lenny said: "So far, geologists are still unable to determine the exact age of the canyon and the detailed process of alluvial." There is no authoritative theory about the reasons for the formation of the Grand Canyon.
The exposed rock formations on the cliffs of the Grand Canyon span a long distance, including Vishnu schist (located at the bottom of the internal gorge) formed 2 billion years ago and Kaibabu limestone (located on the shore) formed 230 million years ago. When the coastline of the original North American continent moved forward or backward repeatedly, many rock layers were deposited in warm shallow seas, coastal beaches or swamps. However, there are exceptions, including Cocochino sandstone deposited in the form of sand dunes in the desert and parts of Supai rock formations.
The reason why the Grand Canyon is so deep and its rock formations (mostly formed below the sea level) are so towering may be attributed to the elevation of the Colorado Plateau of nearly 1500 to 3000 meters about 65 million years ago. This height greatly increases the inclination of the Colorado River and its tributaries, thus speeding up the flow rate and enhancing the ability to cut rocks.
2. Victoria Falls (location: 25.86 degrees east longitude, 0/7.92 degrees south latitude).
Located in the middle reaches of Zambezi River in Africa, between Zambia and Zimbabwe, it is one of the most spectacular waterfalls in the world. The width is about 1.7km and the height is about128 m.
1855 Scottish explorer David? Livingston became the first European to see Victoria Falls and named it after Queen Victoria. Locals call it Mosi-oa Tunya, which means "thunder and smoke".
Victoria Falls is also a part of Mosio Tunia National Park in Zambia and Victoria Falls National Park in Zimbabwe. 1989, UNESCO listed Victoria Falls and these two national parks as world heritage sites. They are one of the most important tourist attractions in southern Africa.
history
It is known that the earliest people who lived near Victoria Falls were the hunting and gathering Koisan people, and later the Tokalaya people settled here. They called Victoria Falls Shongwe, then Ndebele settled here and called Victoria Falls aManza Thunqayo. Finally, Kyle's Rollo called it Mosio Tunia, which means thunderous smoke.
185 1 year Scottish missionary and explorer David? Livingston heard that there was a big waterfall in the interior of Africa and began to look for it. From 1852 to 1856, he explored from the upper reaches of Zambezi River to the coast. 1855 165438+1October16 He became the first European to see this great waterfall. Livingston approached Victoria Falls from upstream. Above the waterfall, he crossed an island, which is called Livingston Island today. Livingston was moved by the sight of Ngone Falls on Zambezi River. He thinks Victoria Waterfall is much more spectacular than the waterfalls upstream: under a cloud of water mist, the Zambezi River seems to suddenly disappear from the ground. After the heavy rain, this kind of water mist can be seen several kilometers away. The closer people get to Victoria Falls, the louder their roar becomes. This miracle has not changed so far. He named it after Queen Victoria. He wrote: "Britain has no such beautiful scenery, and no one can imagine its beauty." No European has ever seen it. Only an angel can fly here to see such a beautiful sight. "
Livingston and John in 1860? Kirk went back to Victoria Falls together and made a detailed study of it. Livingston himself had noticed the formation of this waterfall at that time: "... Zambezi River carved hard granite from the left bank to the right bank." Other early Europeans who reached Victoria Falls were Portuguese explorer Cerpa? Pinto and British painter Thomas? Baines, Baines was also the first person to draw Victoria Falls. Until 1905, the railway reached Victoria Falls, and few people outside arrived here.
1934, protecting 68.6 square kilometers of cross-border areas. Starting from 1972, this area has officially become Mosio Tunia National Park.
Victoria Falls is one of the three largest waterfalls in the world. To be precise, it is a waterfall group with an average annual flow of about 934 cubic meters per second. It consists of five waterfalls, namely Devil Waterfall, Horseshoe Waterfall, Rainbow Waterfall, Main Waterfall and East Waterfall, which are nearly 100 meters long. 65.438+0.5 billion years ago, the rock fracture valley caused by crustal movement just crossed the Sanbixi River, and the river directly poured into the canyon with a length of 72 kilometers and a width of 25 ~ 75 meters, forming the Victoria Waterfall.
The right bank of the waterfall is the shallowest, only 80 meters deep, and the deepest in the middle, reaching 1 10 meters, which is twice that of Niagara Falls. During the full moon, you can see the moon halo through the water mist in the waterfall, and during the day, the water mist causes a rainbow.
So it was David? Livingston wanted to use the Zambezi River as the "Road of God" to Christian the interior of South Africa, but Victoria Falls became an insurmountable barrier on the river. It separates the upper and lower reaches of the river. A lot of water is thrown into the depths here, and then flows out along a winding canyon, and this outflow point is the only outlet of the canyon. Victoria Falls is also the starting point of the middle reaches of Zambezi River. It starts from here, flows through many canyons, and finally ends at Cabra Bassa Dam in Mozambique.
Shuipuxia
The only exit of the canyon waterfall under Victoria Falls is a deep valley about 2/3 distance from the west bank of the waterfall. This deep valley is about 30 meters wide. The whole river flows into this deep valley, with a DC of about120m at first, and then enters a tortuous canyon system. This canyon system is about 80 kilometers long and was carved from granite by waterfalls in the past.
At the first corner, there is a small pool. When there is little water, the water in this pool is shallow and calm. During the flood, there were many slow and huge eddies in the pool. The wall height of the canyon is120m.
railway bridge
In the first section of the canyon, almost perpendicular to the waterfall, there is a railway bridge. It is one of the only five bridges on the Sanbixi River and was completed in April 1905. The span of the bridge is 250m, of which the maximum span is150m. At low tide, the distance between the water surface and the bridge deck is125m. It should be Cecil? The Cape of Good Hope planned by Rhodes is a part of Cairo Railway. Today, there are shuttle buses connecting Victoria Falls, Livingston and bulawayo, and connecting Livingston and Lushaka.
3. Mount Everest
Everest Nepalese:? ), referred to as Mount Everest, is located in the Himalayas on the border between China and Nepal, with an altitude of 8844.43 meters and snow all year round. It is the highest mountain in the world.
name
The Tibetan language is Mount Qomolangma, which means "Mother Earth" and is called Mount Qomolangma. In Tibetan, "Jo-mo" means goddess, and "Langma" should be understood as female elephant (in Tibetan, "Langma" has two meanings: Yanagi Takayama and female elephant). According to myth, Mount Everest is the palace where tshe-ring mched lnga lived.
In the west, this mountain is more commonly called Mount Qomolangma or Mount Qomolangma, in memory of George, the director of Indian Survey Bureau, who was in charge of surveying the Himalayas when Britain occupied Nepal. George Everest [1].
Nepalese name is sagar Mata (? ; Sagarmatha), meaning "goddess of the sky". This name was coined by the Nepalese government in the 1960s. Because the Nepalese people did not name the mountain before, the government did not choose to use transliteration for political reasons.
The lotus posthumous work unearthed in 1258 was named "Lachi", and Sangji, a monk of the Kagyu Sect, praised Mirariba Road as "the most snowy" in songji. 17 17 years, the surveyors of the Qing dynasty surveyed the panoramic view of the royal land in the area of Mount Everest. Mount Everest was named after "Everest Alin", which means "mountain" in Manchu. 1952 China government changed its name to Mount Everest.
height
The State Bureau of Surveying and Mapping of China made the last survey of Mount Everest in 2005. In March 2005, a large-scale scientific research activity on Mount Everest began, which lasted more than two months. On May 22nd, the first batch of climbers successfully climbed to the top at 1 1: 08. On June 9, 2005, the Bureau of Surveying and Mapping announced that the rock surface elevation of Mount Everest should be 844.43m and the ice thickness should be 3.50m [1]. This is the first time to measure the elevation of the rock surface of Mount Everest, which is said to be the most accurate measurement so far, and it is 3.7 meters shorter than the height of 8848.438+03 meters measured by 1975. In order to obtain more accurate authoritative data, the National Bureau of Surveying and Mapping of China adopted the technical scheme of combining classical survey with satellite GPS survey, and used the snow and ice depth radar detector in Everest survey for the first time. There are other sayings that the height of Mount Everest is 8848 meters, 8840 meters, 8850 meters and 8882 meters.
Although Mount Everest is the highest mountain in the world, its summit is not the farthest point from the center of the earth. This special point belongs to Chimborazo Mountain in South America.
Cultural influence
The majestic image of Mount Everest has always had an impact on the local area and even the whole world. The fourth edition of RMB1The back of 0 yuan and the front of 5 yuan are both Mount Everest.
Climb history
192 1 year-the first British mountaineering team was in Charles? Howard. Under the leadership of Lieutenant Colonel Burleigh, he began to climb Mount Everest and reached an altitude of 7000 meters.

4. mammoth cave
Mammoth Cave, located in Mammoth Cave National Park in central Kentucky, USA, is one of the world natural heritages. The mammoth cave is named after the mammoth, an ancient woolly mammoth. By 2006, this "Big Mac" cave has been explored for nearly 600 kilometers. How long is it? It is still being explored. For more than 200 years, explorers have gone wave after wave, and their exploration spirit is engraved in the discovery history of each kilometer of Mammoth Cave.
In mammoth cave, 10 mile is open to tourists. It consists of five layers of 255 caves, which are interconnected from top to bottom, left and right. There are holes in the caves, just like a huge tortuous underground maze. There are 77 underground halls, 3 underground rivers, 7 waterfalls and many underground lakes in these caves, with a total length of nearly 250 kilometers. The mammoth cave is the most famous in the world because it has many strange big caves. Among the 77 underground halls, the tallest one is called "Chief Hall", which is slightly oval, with a length of163m, a width of 87m and a height of 38m. This hall can hold thousands of people. There is a poetic "Star Hall". Its ceiling is made of black oxide containing manganese, which is dotted with many white gypsum crystals. Seen from below, it looks like a sky full of stars.
5. Glacier Bay
Glacier Bay National Park is located in Alaska, 50 miles from Old New Jersey, covering an area of 3.3 million hectares. It is surrounded by steep mountains and can only be reached by boat or plane. There are countless icebergs, whales and kayaks of Eskimos. Tourists in Glacier Bay live in tents or in the countryside of Tian She. According to the inscription, one of the most fascinating landscapes in Glacier Bay National Park is the glacier moving in the huge bay. Moore Glacier was the first scientist to study glaciers carefully. He came here many times from 1879 and was conquered by the beautiful and rich glaciers here. Since Muir's expedition, glaciers have moved far north along coastal bays, and this phenomenon has also been found in other parts of the northern hemisphere.
Muir Glacier, located in Glacier Bay and protruding from the northern end of Alaska, is named after the scientist Muir. The long and narrow glacier bay extends inland about 105 km, and there are more bays on the edge (in fact, these bays are carved by glaciers). Most of these bays are abrupt ice walls, and this ice wall is the tip of an iceberg extending from the hillside to the coast. Since 1982, Moore Glacier has retreated rapidly. With the retreat of glaciers, plants quickly replaced glaciers and covered the surface. In addition to glaciers, wild animals in glaciers also deeply attract tourists from all over the world. The picture shows a group of seals living in the corner of Moore Glacier. Most of these seals have thick and rough skin and a thick layer of fat (usually 1 1- 13cm), which can not only isolate the cold outside, but also store energy for them to cope with food shortage.
Glacier Bay National Park and Reserve is named after 1980 and covers an area of 10784 square kilometers. This national park is not connected with the outside world by road, but it is visited by hundreds of thousands of tourists every year. The glaciers we see now are said to have formed during the Little Ice Age 4000 years ago, not the product of the Pleistocene period between 1 10,000 and1100,000 years. Our cruise ships mainly look at Majerie Glacier and John? Johns Hopkins glacier. These two glaciers are called "tidal glaciers". After long-term accumulation and extrusion, glaciers directly leak into the sea. According to reports, those glaciers slide at a speed of about 7 feet every day, while those facing the sea did not all slide down the mountain foot by foot three or four hundred years ago. These glaciers have formed a wall of ice and snow tens of meters high in the bay. This ice wall collapses from time to time, and sometimes big icebergs fall into the sea. In summer, those big icebergs may take a week or more to melt.
6. Lake Baikal
Lake Baikal (Russian: о? зеро Байка? л), located in Irkutsk and Buryatia in southern Siberia, Russia, only100km away from the border of Mongolia, is the birthplace of many ethnic groups in East Asia.
geography
Lake Baikal is crescent-shaped, with a length of 636 kilometers, a width of 24-80 kilometers and an area of 365,438+0,494 square kilometers. It is the largest freshwater lake in Asia and the seventh largest lake in the world. It is a tectonic lake with frequent earthquakes and many hot springs along the coast. The basin covers an area of 560,000 square kilometers, and there are as many as 336 rivers flowing into it, of which only one Angara River is its outlet.
Lake Baikal is the deepest lake in the world. The deepest point is measured from1620m (5315ft) to1940m (6365ft), with an average depth of 758m. The lake is 456m above sea level, and the deepest lake bed is-1484m above sea level. Lake Baikal is also the oldest lake in the world. According to research, it has existed on the earth for more than 25 million years.
Lake Baikal has the only freshwater seals in the world: Lake Baikal seal and ACIPENSER schrenckii.
history
China called Lake Baikal the North Sea in ancient times. During the Han dynasty, it belonged to the activities of Xiongnu. The famous story of Su Wu herding sheep happened in Lake Baikal. After the Han Dynasty, after the Three Kingdoms, the Jin Dynasty, the Five Dynasties and the Tang and Song Dynasties, ancient nomadic peoples such as Xianbei, Wuhuan, Zile, Qidan and Uighur lived in Lake Baikal. These ethnic groups are usually independent of the Central Plains dynasty and even invaded, and sometimes they surrender to the central authorities. For example, in the heyday of the Tang Dynasty, Uighurs surrendered. By the time of the rise of Mongolia, as an area very close to the Selenger River, the prosperous place of Mongolia (note: Selenger River is the largest river flowing into Lake Baikal), the political, economic and strategic position of Lake Baikal is becoming more and more important.
After the Ming and Yuan Dynasties, Mongolia retreated to the north of the Great Wall and split in two. Vara, Tatar and Lake Baikal are all under the rule of Mongolia.
When the Qing Dynasty rose at the end of the Ming Dynasty, except Monan Mongolia, which is now Inner Mongolia, Mobei and Moxi Mongolia were still at arm's length from the whole Chinese nation. Before the Qing Dynasty entered the customs, today's outer Mongolia lived in Khalkha Mongolia, Lake Baikal lived in Buryatia Mongolia, and Moxi lived in today's Xinjiang. The center and core area of Buryat Mongols' activities is Lake Baikal.
1697 and 1757, Khalkha Mongolia and Junggar Mongolia were controlled or conquered by the Qing government respectively. However, in the Sino-Russian Nebuchadnezzar Treaty, the area east of Lake Baikal belonging to Buryatia Mongolia was allocated to Russia.
1On June 30th, 908, the Tunguska Big Bang occurred 800 kilometers northwest of the lake, partially affecting the forest near the lake.
7. Yellowstone National Park
Yellowstone National Park (English: Yellowstone National Park) is the first national park in the world, established at 1872. Yellowstone National Park is located in the northwest corner of Wyoming in the midwest of the United States, extending northwest to Idaho and Montana, covering an area of 7,988 square kilometers. This area was originally a sacred place for Indians, but it became the earliest national park in the world because of the excavation of American explorers Lewis and Clark. 1978 is listed as a world natural heritage.
The height of the park rises from 53 14 feet (1.620 meters) at the northern entrance (Gardner, Montana) to 1 1.358 feet (3,462 meters) at Eagle Peak, the highest point in the southeast of the park. There are the largest geysers in the world in the vast natural forest of Huangshi National Park, where more than half of the geysers in the world are located. These geothermal wonders prove the existence of the largest active volcano in the world. Yellowstone National Park takes the bear as its symbol. There are about 200 black bears and 100 grizzly bears in the park.
The dynamic landscape of Huangshi is divided into three aspects: hot air zone, yellowstone river river basin and wildlife.
Hot gas zone
The geothermal terrain of Yellowstone National Park is actually a huge crater. This active volcano has never erupted in human history, but it has erupted three times in geological times.
This volcano is different from most volcanoes in the world. It is not at the junction of two plates in the crust. It is the same as Hawaii volcano principle, and it is a hot spot in the mantle. When the plate drifts, the hot spots don't move, just like the feeling of hot spots moving on the plate. The Yellowstone hotspot originated in the northeast corner of Oregon, and today it passes through Idaho to the northwest corner of Wyoming, and then it will go to Montana and North Dakota. A series of extinct volcanoes were formed where the hot spots passed, and the lava erupted by these volcanoes in the past formed today's Shehe Plateau.
Before the Yellowstone hotspot came to the Rocky Mountains, the landform of Yellowstone National Park was similar to that of grand teton national park, which borders it today. In the future, after the Yellowstone hotspot leaves, it will be like the crater of the Moon National Monument in Idaho today.
The specific performance of Huangshi hot spot is the hot air belt on the surface. There are underground hot craters that constantly replenish hot springs, fountains that erupt constantly, geysers that erupt regularly or irregularly, steam geysers that only emit steam but don't erupt, and even clay pots that erupt only once every few hundred years. In short, there are all kinds. These waters are very hot and rich in hydrogen sulfide [[H2S]], which attracts all kinds of bacteria to live here. These bacteria have different bright colors, which make the hot air area colorful and dazzling. Although these geothermal landforms are widely distributed throughout Huangshi National Park, they are mainly concentrated in several basins.
However, they are not static. With the change of the earth's crust, the original active place may suddenly quiet down. A quiet and nameless place may also be a blockbuster. The mammoth hot spring in the northwest corner of the park is an example: originally, several hot springs flowed down the hillside one by one, stained with various bacteria, forming a very beautiful big step; However, in a crustal change in 2002, most of the hot springs here stopped flowing, and the dead bacteria turned into gray powder, leaving it on the dry steps, reflecting the dazzling sunshine and turning it into a barren land.
The geothermal basins in the park are mainly concentrated in the southern region, including the upper geyser basin, the middle geyser basin and the lower geyser basin, among which the most famous are the old faithful spring and the big prism spring. Old faithful spring erupts every 30 to 120 minutes, with an average of 70 to 90 minutes. Each eruption lasts from one and a half minutes to five and a half minutes, and the eruption height is about 50 meters. People have mastered the mathematical relationship between "the length of each eruption" and "the time interval from the next eruption" of the old faithful spring, so the time of the next eruption can be predicted quite accurately every time. Old Faithful Spring is called Old Faithful Spring because it erupts day and night, goes to Qiu Lai in spring, and is punctual every year.
Recently, the geothermal energy of Huangshi has shown signs of moving slightly northward. The old faithful spring may be really old, and the average interval between each eruption is getting longer and longer. On the contrary, norris geyser basin in the west of the park is becoming more and more active. Among them, the steamboat geyser has changed from spraying once for a long time to spraying once almost every day; There are also some geysers whose eruption heights have hit record highs. Some geysers only spray once every few months, and their eruption height is several times that of the old faithful spring. Norris geyser basin is really a place worthy of attention.
Yellowstone river river basin
Due to geothermal energy, Yellowstone National Park has hot springs everywhere, even under submerged lakes or rivers. Therefore, the water in Huangshi is rich in minerals, so it is very toxic. Even if it is cooked, it is not suitable for human consumption. The largest river in Yellowstone National Park is yellowstone river, which starts from yellowstone lake in the south in the east of the park, flows northward to form a slow-moving stream, and then suddenly dives from the abyss to the Yellowstone Grand Canyon, forming the upper Yellowstone Waterfall and the lower Yellowstone Waterfall.
Yellowstone lake is the largest lake in Yellowstone National Park. Speedboats are allowed on the lake except in some places in the south. The shape of the lake is like a hand, and a place like a thumb in the west is called the west thumb, which is one of the famous hot air areas. When you look at yellowstone lake from the west thumb, you will find that the lake on the shore is colorful and the color is constantly changing, which is a sign that the hot fountain at the bottom of the lake is erupting. This discoloration can also be seen in many other places in Huangshi River. The highway goes along the west bank of the lake, and the other side is relatively high, with a row of snow-capped mountains in the distance. The lakes and mountains may not be as magnificent as the Grand Deton National Park bordering Yellowstone National Park, but it is already amazing.
Yellowstone lake flows northward, forming yellowstone river. Fishing Bridge is basically located at the boundary between yellowstone lake and yellowstone river, and used to be a fishing resort. Now in order to protect the natural ecology here, fishing is no longer allowed. If you want to fish, you can move to other nearby rivers, such as Huodong River. In the following time, yellowstone river gradually became a winding river, flowing quietly among the green hills, attracting many wild animals. There is no obvious rock boundary on the river bank here, so many places along the river seem to be covered with grass or other shrubs. If you really step on it, it's probably water. In winter, it's all white here, and occasionally a group of wolves or other creatures haunt it.
Not long after flowing to the northwest, yellowstone river suddenly turned right, then immediately plunged, forming two Yellowstone waterfalls, which washed out the spectacular Yellowstone Grand Canyon. The cliffs on both sides of the Yellowstone Grand Canyon are yellow, which should be stained with sulfur.
wild animals
The large wild mammals inhabiting Yellowstone National Park are (for the convenience of tourists):
Bison: Adult bison weigh more than 65,438+0,000 kg. Although it is large, it is very docile, and it is the animal that causes the most casualties among tourists.
Elk: Adult red deer weighs 300 kilograms. Elk and red deer, but not Asian elk or red deer. Bucks have forked horns and fall off every winter. The doe has no horns.
Mule deer
white tailed deer
black bear
Moose: also known as elk and ape, but not Asian elk (that is, ape). Slightly smaller than the bighorn deer, the antlers are forked and the bottom is connected like a palm. The doe has no horns.
Coyote: Also known as coyote and American wild dog.
Pronghorn: The fastest wild animal in America
Grizzly bear beer
bighorn
Grey Wolf: In the past, all wolves in Yellowstone National Park were killed. In recent years, wolves have been introduced into the park to control the population of American bighorn deer.
