Question

what are metamorphic rocks​

Answer 1

hey...

A metamorphic rock is a type of rock which has been changed by extreme heat and pressure. Its name is from 'morph' (meaning form), and 'meta' (meaning change). The original rock gets heated (temperatures greater than 150 to 200 °C) and pressured (1500 bars). This causes profound physical and/or chemical change.

Metamorphic rocks are created by the physical or chemical alteration by heat and pressure of an existing igneous(formed through the cooling and solidification of magma or lava) or sedimentary(formed from the sand, stones, mud) material into a denser form.
