Question

Which part of the rock cycle can only occur because of thermal convection? metamorphic rock changing to sedimentary rock magma changing to igneous rock sediment changing to sedimentary rock igneous rock changing to metamorphic rock

Answer 1

Answer:

magma changing to igneous rock

Explanation:

In rock formation, there are several processes involved which could include sedimentation, melting, crystallization, etc but there is a part of the rock cycle that can only occur because of thermal convection which is magma changing to igneous rock.

This occurs when the heat from inside the earth and cooler temperature moves the rock in its liquid state which is known as convection and can also be defined as a cycle of heat transfer from where the hot material rises and the cool material condenses.
