Question

2) Write short notes on:
A. Mantle​

Answer 1

Explanation:

The mantle is the mostly-solid bulk of Earth's interior. The mantle lies between Earth's dense, super-heated core and its thin outer layer, the crust. The mantle is about 2,900 kilometers (1,802 miles) thick, and makes up a whopping 84% of Earth's total volume. ... Over millions of years, the mantle cooledThe 3 main layers are the core, mantle and crust. The mantle is composed of the mesosphere and the asthenosphere and the uppermost part of the mantle.Earth's mantle plays an important role in the evolution of the crust and provides the thermal and mechanical driving forces for plate tectonics. Heat liberated by the core is transferred into the mantle where most of it (>90%) is convected through the mantle to the base of the lithosphere.
