How in metamorphic rock formed?

Answer 1

Metamorphic rocks are rocks formed from igneous, sedimentary and even other metamorphic rocks. Heat, pressure and chemical action can cause a rock to change into another rock. Pressure from the rocks on top of them squeezes and folds the rock. Their grains come close together and they become less porous. Heat and chemicals may cause changes in the arrangement of mineral particles or new minerals may be formed.

Answer 2

Metamorphic rocks are formed from existing rock types that undergo changes in temperature, pressure, or chemical conditions deep within the Earth's crust. This process, known as metamorphism, causes the original rock to recrystallize into a new rock type with different mineral composition and texture. Factors such as temperature, pressure, and the presence of fluids play a key role in determining the final characteristics of the metamorphic rock formed.
