The earth's crust is made up of various types of rocks, differing from one another in texture, structure, colour, permeability, mode of occurrence, and degree of resistance to denudation.
Generally speaking, all rocks may be classified into three major groups:
- Igneous Rocks
- Sedimentary Rocks
- Metamorphic Rocks
1. Igneous Rocks:
- Igneous rocks are formed by the cooling and solidification of molten rock (magma) from beneath the earth's crust.
- Example: Granite, Gabbro, Basalt, etc.
2. Sedimentary Rocks:
- Sedimentary rocks are formed by the process of weathering and cementation or precipitation on the Earth's surface.
- Example: Sandstones, Kankar, shales, limestones, Mudstones, laterite, etc
3. Metamorphic Rocks:
- Formed when rocks are subjected to high heat, high-pressure changes inside the Earth.
- Example: Gneissoid, slate, schist, marble, quartzite, etc.
