What are metamorphic rocks?​

Answer 1

Answer:

Metamorphic rocks started out as some other type of rock, but have been substantially changed from their original igneous, sedimentary, or earlier metamorphic form. Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors.

Answer 2

Answer:

The word Metamorphic is derived from the Greek word Metamorphose which means the change of form. Metamorphic rocks are the rocks that get formed under great heat and pressure. They are formed when Igneous and sedimentary rocks are subjected to heat and pressure. For example, clay changes to slate and limestone into marble.
