GEOLOGY

Detailed explanation-1: -The process of metamorphism does not melt the rocks, but instead transforms them into denser, more compact rocks. New minerals are created either by rearrangement of mineral components or by reactions with fluids that enter the rocks.

Detailed explanation-2: -In order to create metamorphic rock, it is vital that the existing rock remain solid and not melt. If there is too much heat or pressure, the rock will melt and become magma. This will result in the formation of an igneous rock, not a metamorphic rock.

Detailed explanation-3: -Metamorphic rocks are igneous, sedimentary, or metamorphic rocks that have been changed or altered in response to deep burial, intense heat and pressure without melting the rock or interaction with hot fluids.

Detailed explanation-4: -When metamorphic rocks undergo the effects of intense heat and pressure, they are converted into igneous rocks. Thus, the study of metamorphic rocks allow us to better understand the temperatures and pressure present within the Earth’s crust.
