Igneous rock (igneous from Latin igneus 'fiery'), or magmatic rock, is one of the three main rock types, the others being sedimentary and metamorphic. Igneous rocks are formed through the cooling and solidification of magma or lava. The magma can be derived from partial melts of existing rocks in either a planet's mantle or crust.

Learn what igneous rocks are, how they are formed, and what types of igneous rocks exist. Find out the characteristics, examples, and uses of igneous rocks with BYJU'S Physics and Earth Science videos and quizzes.
- Igneous rocks are formed from the magma and begin the rock cycle, hence they are known as primary rocks.
- Basalt is the most common type of igneous rock. The majority of the ocean floor is composed of basalt.
- Diorite, granite, pegmatite are intrusive igneous rocks.
- Basalt, tuff, pumice are extrusive rocks.
- Pumice is a light-coloured, extremely porous igneous rock that is formed during explosive volcanic eruptions.
