Question

What are the three group of the rocks on the basis of the origin ? what are the geologic processes involved in the formation of the each group?

Answer 1

Answer:

The three main types, or classes, of rock are sedimentary, metamorphic, and igneous.

Sedimentary rocks:-Sedimentary rocks are types of rock that are formed by the accumulation or deposition of small particles and subsequent cementation of mineral or organic particles on the floor of oceans or other bodies of water at the Earth's surface.

Metamorphic rocks:-Metamorphic rocks have been modified by heat, pressure, and chemical processes, usually while buried deep below Earth's surface.

Igneous rocks:- Igneous rocks are formed from the solidification of molten lava/rock material.

Answer 2

The three main rock types are igneous, metamorphic and sedimentary. The three processes that change one rock to another are crystallization, metamorphism, and erosion and sedimentation. Any rock can transform into any other rock by passing through one or more of these processes. This creates the rock cycle.
