Question

Answer 1

As we all know, it is not at all possible to go inside earth’s interior that is about 6370 km but to know about it, we always rely on direct and indirect sources.

Some of the direct and indirect sources are given below:

1. Direct Sources: Molten Lava from volcanic eruption, rocks that are obtained from mining and other drilling activities and meteors falling on earth.

2. Indirect Sources: These are the activities that we assume and we already know.

These also come from the direct activities and sources.
