1. Earth science is also called Earth science for short. It is one of the six basic natural disciplines of mathematics, physics, chemistry, astronomy, geoscience and biology. Earth science is a basic discipline to study the process, change and interaction of the earth system (including atmosphere, hydrosphere, lithosphere, biosphere and sun-earth space). At present, it mainly includes geology, geophysics, geography, meteorology, hydrology, oceanography, pedology, environmental geoscience and other derivative disciplines. Earth science has spanned hundreds of millions of years in Wan Li and almost spread to other fields of natural science. The understanding of the earth is closely related to the origin, history, culture and even progress of this world civilization.

2. According to scientific calculation, the age of the universe is 65.438+0.4 billion years, and the age of the earth is 4.6 billion years. Compared with human's short life, human just blinks. During this long time, there have been geological processes such as biological evolution, land-sea change and mountain formation on the earth, which are extremely slow and usually take millions or tens of millions of years to complete.

Because earth science involves a long time, studying earth science is conducive to cultivating our patience, perseverance and overall concept.

4. At the same time, the vastness of space determines that geoscientists should first observe nature in the wild and study it as a natural laboratory, but it is impossible to move huge and complex nature indoors for research. Field investigation is the most important and basic link in earth science work, and it can obtain the first-hand information of the research object. Only by carefully and pertinently collecting the original data can it be possible to solve the earth science problems correctly.
