What is Earth Science?
Earth science is the branch of science pertaining to the study of the origin, structure, and phenomena of the planet Earth. Earth science is an all-embracing term, for the sciences related to the study of the earth and of the universe around it, making it a wide scientific discipline, covering all facets of how the earth is. It is a special case in planetary science, as the earth is the only known life-bearing planet. Earth science is also known as geoscience.

Earth Sciences - Four Branches
The basic four branches of earth science include:
  1. Geology - study of the earth
  2. Meteorology - study of the atmosphere, weather and climate
  3. Oceanography - study of the oceans
  4. Astronomy - study of the universe
These earth science branches make use of several science disciplines like geography, geophysics, geodesy, physics, chemistry, biology, mathematics, chronology, ecology, environmental science, geomatics, climatology, geomorphology, biogeology, soil science, geochemistry, weather, global warming, natural disasters and hydrology to build a quantitative understanding of the Earth system.
