Question

How metamorphic rocks are formed?

Answer 1

Metamorphic rocks form when existing igneous or sedimentary rocks undergo changes due to high pressure, high temperature, or both. This causes their minerals to recrystallize and reorganize, changing the rock’s texture and properties. These rocks often form deep in the earth due to tectonic activity or contact with hot magma, resulting in harder, denser, and sometimes darker rocks like marble, slate, and quartzite.
