Question

The most accessible part lying at the centre of the earth?

Answer 1

It is not possible to know about the earth’s interior by direct observations because of the huge size and the changing nature of its interior composition.

It is an almost impossible distance for the humans to reach till the centre of the earth (The earth’s radius is 6,370 km).

Through mining and drilling operations we have been able to observe the earth’s interior directly only up to a depth of few kilometers.

The rapid increase in temperature below the earth’s surface is mainly responsible for setting a limit to direct observations inside the earth.

But still, through some direct and indirect sources, the scientists have a fair idea about how the earth’s interior look like.
