The earth’s interior structure has a direct impact on the earth’s surface. The study of internal structure of the earth is necessary in geography because the various topographies found on Earth’s surface are the result of geological processes. Occurring inside the earth.
Exogenous processes occurring in the exterior parts of the Earth and endogenous processes occurring in the interior parts bring changes on the Earth’s surface. The terrestrial form is the result of these transformational forces. Human activity and order of life are linked to these forces and landscapes. That is why, studying the interior structure of the Earth is essential.
