Granite is an igneous rock that forms when magma cools relatively slowly underground. This will result in the formation of an igneous rock, not a metamorphic rock.Ĭonsider how granite changes form. If there is too much heat or pressure, the rock will melt and become magma. In order to create metamorphic rock, it is vital that the existing rock remain solid and not melt.

These conditions are most often found either deep in Earth’s crust or at plate boundaries where tectonic plates collide. Usually, all three of these circumstances are met. The existing rock must be exposed to high heat, high pressure, or to a hot, mineral-rich fluid. The conditions required to form a metamorphic rock are very specific. Then, due to various conditions within the Earth, the existing rock was changed into a new kind of metamorphic rock. A metamorphic rock, on the other hand, began as a rock-either a sedimentary, igneous, or even a different sort of metamorphic rock. Igneous rocks formed when liquid magma or lava-magma that has emerged onto the surface of the Earth-cooled and hardened. Sedimentary rocks were originally sediments, which were compacted under high pressure. Sedimentary and igneous rocks began as something other than rock. In the rock cycle, there are three different types of rocks: sedimentary, igneous, and metamorphic. Rocks that undergo a change to form a new rock are referred to as metamorphic rocks.

Even rocks, a seemingly constant substance, can change into a new type of rock.

However, the word “metamorphosis” is a broad term that indicates a change from one thing to another. The term “metamorphosis” is most often used in reference to the process of a caterpillar changing into a butterfly.
