Melting in the mantle is a result of:

A) decompression
B) conduction
C) convection
D) compression

Decompression

The reduction in pressure exerted on a material, often leading to changes in its physical state or phase.

Melting Mantle

The process in which the Earth's mantle, the layer between the crust and the core, experiences partial melting to form magma.

Conduction

The transfer of heat or electricity through a substance without substantial movement of the substance itself.

Illustrate the steps involved in the genesis and maturation of magma, with a focus on partial melting and the diversification of magma types.

Verified Answer

Final Answer :

Explanation :

Decompression melting occurs when hot mantle rock rises and the pressure decreases, allowing the rock to melt without necessarily adding heat.
