Branches of Earth Science

Branches of Earth Science

Introduction: Earth is our home. We depend on its atmosphere for oxygen. We need its water to sustain us. We use its materials to build shelter for protection. Earth science is the study of our planet, its formation, and its natural history. This includes how human activities impact Earth. Earth science is an interdisciplinary science. This means that understanding Earth's systems requires knowledge of all of the sciences. 

Since the Earth is complex, there are many branches, or fields, of Earth science. These can be grouped under four main groups: Geology, Oceanography, Meteorology and Climatology, and Astronomy.
