(b) 2000 and 5371 km

(c) 2500 and 4771 km

(d) 2000 and 5000 km

The question was posed to me by my school teacher while I was bunking the class.

Query is from The Mantle, The Core in chapter Internal Structure of the Earth of Engineering Geology

Answer 1

Right answer is (a) 2900 and 6371 km

The best I can explain: The mantle extends up to the depth of 2900 km and from that depth it is the core that is said to be present and the radius of the Earth is 6371 km and hence the core is said to extend till 6371 km.
