Question

Explain the source of knowing about the interior of the earth

Answer 1

Answer:

I think The earth’s radius is 6370 km. Going beyond a limit is not possible as it is very hot at this depth. In such conditions the knowledge about the interior of the earth is mainly based on estimates and inferences.

The knowledge about interior of the earth is obtained through direct sources and indirect sources. Direct sources include rock materials from mining areas and molten magma from volcanic eruptions. Besides, scientists are working on “Deep Ocean drilling Project” and “Integrated Ocean Drilling Project”. These projects have provided information about interior of Earth through analysis of materials collected at different depths.

And

Indirect sources include meteors that at times reach the earth, gravitation, magnetic field, and seismic activity. Most of our information about earth’s interior has come from seismic studies.
