The overarching goal of Earth science is to gain an understanding of Earth's existing features and past evolution and to put that understanding to good use for humans. This means that a scientist's primary goal in his or her field is to collect data and make hypotheses to explain the planet's features and evolution, as well as devise methods of comparing the relative merits of competing hypotheses. It's via this process that the most logical, palatable, and long-lasting concepts are generated.
Definition
The study of the solid Earth, its oceans, and the air that encircles it are known as Earth sciences. Geology, hydrology, and atmospheric science are all covered.
There have been four and a half billion years of biotic evolution that have been studied in Earth science.
Because of this, understanding these occurrences is vital to the survival of life on Earth.

Besides the surface of the solid Earth, the physical environment in which people live comprises not only the ground under it, but also the ocean and air above it. Demand for resources, natural disaster losses as well as environmental pollution are growing as the world population continues to grow. We can only continue to live if we have a thorough scientific grasp of the interconnections between the Earth's crust, oceans, atmosphere, and biosphere. Where these two conditions meet, life thrives or dies on the surface of the Earth
