Answer 1

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).

Answer 2

$\huge\underline\mathfrak\pink{Answer:-}$

The word 'metamorphosis' means change of form. Igneous and sedimentary rocks change their form under very high temperature or pressure. Such 'changed' rocks are known as metamorphic rocks .Metamorphic rocks are usually very hard.Some common examples of such rocks are marble (formed from limestone), slate (formed from shale), and quartzite (formed from sandstone). Rocks undergo a cycle of transformation, often called the rock cycle. Magma rising from depths below the earth's surface produces igneous rocks. The breaking down of different types of rocks produces sediments from which sedimentary rocks are formed. Extreme heat and pressure may cause igneous and sedimentary rocks to form metamorphic rocks. When rocks are melted by heat, new magma is formed.
