Question

Explain the formation of metamorphic rocks ​

Answer 1

Metamorphic rocks arise from the transformation of existing rock types, in a process called metamorphism, which means "change in form". The original rock is subjected to heat and pressure, causing profound physical or chemical change. The protolith may be a sedimentary, igneous, or existing metamorphic rock.

Answer 2

when igneous and sedimentary rocks undergo metamorphosis during which their colour texture hardness and mineral composition get changed due to high temperature and pressure forms meristematic rocks
