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

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.

Rock cycle is a phase of rocks that changes from one form to another. These rocks undergo changes in their chemical and physical properties. The rocks cycle starts with igneous rocks and moves to secondary rocks such as sedimentary and metamorphic.

The part of rock cycle that includes the thermal changes such as convection

The conversions of he rock into metamorphic rocks due to the process of heat and pressure. Hence the option igneous rocks change to metamorphic rock is correct.
