What are the different types of rocks? How will they form?
Rocks are mineral aggregates with a combination of properties of all the mineral traces. Any unique combination of chemical composition, mineralogy, grain size, texture, or other distinguishing characteristics can describe rock types
Types of Rocks
The three types of rocks are explained below.
Igneous Rock
Igneous rock is one of the three main rock types. Igneous rock is formed through the cooling and solidification of magma or lava. Igneous rock may form with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.
Examples: Basalt, Mica and quartz, Diorite, etc.
Sedimentary rocks
Deposition and cementation of rocks and minerals within water bodies and at the Earth’s surface produce sedimentary rocks. Rocks of the earth’s surface area exposed to denudation agents and are broken up into various sizes of fragments. These fragments are carried by various exogenous agencies and deposited. These deposits through compaction turn into rocks. This process is called lithification. In several sedimentary rocks, the layers of deposits maintain their characteristics even after lithification.
Examples – Sandstone, shale, etc.
Metamorphic Rocks
Metamorphic rocks are created deep beneath the Earth’s surface and are subjected to high temperatures and enormous pressure from the rock layers above them.
Examples – Quartzite, marble, slate, etc
