How did the caste system
give power?

I'm assuming you're talking about the Indian Caste System.

Explanation:

The caste system gave power to people by basically telling you "no you cannot be better and you should not try to be better." This system was removed at one point but the shadow of the system is damaging Indian society to this day.

whats the question? im not quite understanding your question.

well that depends on how deep the hole is. you'd first go through te crust of the earth, then the upper mantle, then the lower mantle then the outer core, then the inner cor then you'd be stuck in the core to melt.
