About Geology and Geophysics

By quantitative physical methods, Geophysics is the study of the Earth. The study of the Earth is called Geology. It includes composition and material, structure, processes, and history. It has several specialised areas of research. It is an applied science and consists of the Earth’s interior, crust, oceans, atmosphere, and magnetosphere. Geology and Geophysics also included in the GATE exam.
