Igneous rocks are rocks that have solidified from magma or lava. Magma is molten rock that is located beneath the Earth's surface, while lava is molten rock that has erupted onto the surface. When magma or lava cools and solidifies, it forms igneous rocks. Igneous rocks are classified based on their texture and mineral composition, with the two main categories being intrusive (formed from magma that cools slowly beneath the Earth's surface) and extrusive (formed from lava that cools quickly on the surface). Some common examples of igneous rocks include granite, basalt, and pumice. Igneous rocks play an important role in the Earth's geological processes, including the formation of mountain ranges, the creation of new crust, and the recycling of old crust via plate tectonics.
Igneous rock, 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.
