Question 2: Where is Sister Glacier in Mini World? Digging gravel has a chance to get (that is, gray sand). After the gravel is dug out, it is recommended to spray gravel or flint. It is suggested that the excavated gravel should be made into a column, the bottom gravel should be dug with a torch and set on fire at the moment of excavation and explosion. The gravel on it will touch the torch and everything will explode. You just need to pick it up next to it and repeat this operation to get a lot of flint.
Question 3: How does famine eliminate the water left by mini-glaciers? You can wait until it freezes next winter, then smash it, and it will be gone.
Hope to adopt, thank you.
Question 4: When did the last ice age end? The late Cenozoic Great Ice Age is the latest Great Ice Age in the history of the earth. Since the Neogene, there has been an alternation of glacial and interglacial periods, which has continued to this day. As early as Oligocene, the Antarctic ice sheet began to appear. In the middle Miocene, the ice sheet had reached a certain scale, and it was the first area to enter the ice age. Glacier environment in the early Quaternary spread all over the world, reaching its peak in the middle period, so the Late Cenozoic Great Ice Age mainly refers to the Quaternary Ice Age. At that time, there were two ice sheets in the northern hemisphere, Scandinavian ice sheet and Lauren ice sheet in North America. The southern boundary of the former reaches 50 north latitude, while the latter reaches about 38 north latitude. In addition, in some high mountain areas in the middle and low latitudes, foothill glaciers or small ice caps have developed. About 8000 ~ 10000 years ago, global warming, a large number of glaciers and ice sheets disappeared or contracted, and the earth entered the post-glacial period. However, the glaciers and ice sheets on the mainland have not completely disappeared.
Question 5: Some scientists say that the sun will hibernate in 2030 and enter the Little Ice Age. Is it true?/You don't say. The Daily Mail website reported that scientists recently warned that the sun will enter a "dormant period" in 2030, which will bring the earth into a "mini ice age". According to valentina? According to the research results published by Professor Zarkov and his research team at the National Astronomical Conference held by the Royal Astronomical Society in Landno, Wales, the solar activity will be reduced by 60% around 2030. This is reminiscent of the movie Snow Country Train, which is set in the extreme cold of the earth. If the earth really falls into extreme cold, the impact on human society will definitely be turned upside down.
In ancient times, the earth once entered an ice age. There is a saying that in the Ice Age, which began about195,000 years ago, ancient wise men just appeared, and the harsh environment caused by drastic climate change destroyed almost all races on the earth, only a few humans survived, and those who survived the ice disaster became our ancestors.
Question 6: 800-word scientific papers. Come on, come on! The relationship between human or animal survival and plants
Not long ago, our family moved into a new house. Just moved home, my uncle and aunt sent some pots of flowers and trees. Bonsai is placed at the door, living room, room and balcony. I said to my father, "We have a botanical garden at home. Why do we have so many plants? " Dad smiled and said, "Plants can create an atmosphere and purify the air. People and animals cannot do without them. " People or animals cannot live without plants? Why can't people or animals live without plants? I'll be skeptical. Decided to do a few small experiments to prove the problem.
On Sunday, I caught two mice from the garage. These two poor little mice will be my experiments. They have been struggling, and the round disposable film tablecloth stared at me with small eyes. I put the first mouse in a big fish tank and sealed the glass bottle tightly, for fear that the air in the bottle would communicate with the outside air. I watched carefully and saw the little mouse running quickly around the bottom of the cylinder against the wall. Hey, isn't the mouse alive and well? Isn't it true what dad said? However, in a few minutes, I saw the little mouse winding slower and slower until it was stagnant and dying. Suddenly, I gently removed the disposable film tablecloth, grabbed the first mouse, put the second mouse in, and moved into four pots of leafy plants. Then gently cover the disposable film tablecloth. I kept patting the fish tank and saw the little mouse scurrying about in panic. After a long time, I don't want to die. This experiment proves that plants can transport the oxygen that animals need.
In order to further prove the dependence of humans and animals on plants. I came to a feed processing factory near our hometown. The air there is full of dust noise, which makes me cough. I feel very uncomfortable. Then, I ran to a bamboo forest behind our house. It is a place with fresh air, and I feel extremely refreshing. This experiment proves that plants can purify the air. Let people breathe smoothly.
These two experiments prove that the survival of human beings and animals is closely related to plants. How scientific is this? Our scientific and technological team came to the library to consult a lot of scientific and technological books, and also went to the electronic north reading room of the school for online inquiry, and summarized the following points: ① People must rely on plants to provide oxygen, and only plants can make oxygen. If a person doesn't eat or drink for a few days, he may die in a few minutes. Oxygen is the first need of human life activities! An adult breathes about 20,000 times a day, inhaling 0.75 kg of oxygen and exhaling 0.9 kg of carbon dioxide. (2) Breathing of animals and plants and burning of substances also consume oxygen and release carbon dioxide. So, isn't there more oxygen in the air every day? Don't! The reason why there has never been such a crisis between heaven and earth is that plants are both "factories" of natural oxygen and "broad markets" of carbon dioxide. According to statistics, 1 hectare of broad-leaved forest can produce 750 kilograms of oxygen and eat 1 1,000 kilograms of carbon dioxide every day during the growing season. Therefore, as long as there are 6,543,800 square meters of trees, it can supply a person with oxygen demand and absorb exhaled carbon dioxide. Because there are plants that constantly supplement oxygen, the oxygen in the air can be kept basically constant. On the contrary, if there are no plants, the oxygen on the earth can be used up in about 500 years.
Therefore, human beings and animals can sustain life, and the oxygen needed for activities must be attributed to green plants. Plants are closely related to our human and animal lives. Let's protect plants from now on!
