Answer 1

Answer:

There are 3 types of rocks on the basis on formation.

Namely:-

1)Igneous

2)Sedimentary

3)Metamorphic

Explanation:

Igneous rocks:-

• Igneous rocks are formed by direct cooling of magma.
• Igneous rocks are formed by exothermal process which includes the loss of heat.

Sedimentary Rocks:-

• Sedimentary rocks are formed by the process of Erosion, Deposition and compaction where the small bits of rock are settled and compressed to form the rock.

Metamorphic rocks:-

• Metamorphic rocks are formed by the intense pressure on existing rocks.
• This will effect the texture and hardness of rock
