Question

List five processes by which rocks can change from one form to another?

Answer 1

Answer:

The five process bu which rocks can change from one form to another are -

1. Weathering   2.  Metamorphism  3. Cooling and crystallization  4. Lithification of sediments  5. Igneous rocks change into metamorphic rocks

Explanation:

The processes by which rocks can change from one form to another are as follows :

1. Weathering : It wears/breaks down the rocks at the surface of Earth’s into smaller pieces.

2. Metamorphism : This changes the entire texture as well as the mineral composition of the rock under conditions of extremely high temperature and pressure.

3. Cooling and crystallization from a molten magma material results in the generation of igneous rocks.

4. Lithification of sediments with proper compaction and cementation leads to the formation of consolidated sedimentary rocks.

5. Igneous rocks change into metamorphic rocks when subjected to high temperature and pressure conditions deep inside the Earth.
