Igneous Rocks:
Igneous rocks form when magma (molten rock) cools and crystallizes, either at volcanoes on the surface of the Earth or while the melted rock is still inside the crust.
The two main types of igneous rocks are extrusive and intrusive.
Example: - Granite, Basalt, Pumice and pegmatite etc.
Sedimentary Rocks:
Sedimentary rocks are formed by the deposition and subsequent cementation of the material at the Earth’s surface within the bodies of water.
Examples: - Limestone, Chalk, Clay, Sandstone, Shale etc.
Metamorphic Rocks:
Metamorphic rocks arise from the transformation of existing rock types, in a process called metamorphism.
Examples: - Gneiss, Quartzite, Slate, Schist, Quartzite and marble etc.
