Question

Igneous and metamorphic rock can be buried and undergo tremendous
heating and stress. What is the process of transformation of one rock type
into another?
​

Answer 1

Answer:

The process of transformation of rock of one type into another is called as metamorphism.

Explanation:

• Metamorphism : Metamorphism is the process of conversion of one type of rocks into another type under the effect of high temperature and pressure.
• Igneous and metamorphic rock undergo vital changes in their composition, atomic arrangement and physical properties under high temperature and pressure. Consequently a new type of rock is formed known as metamorphic rocks. Marble , gneiss, schist, quartzite, Phyllite are some common rocks belonging to the family of metamorphic rocks.

• Igneous rocks are formed after the cooling of magma either inside or outside the earth surface.
