What type of rock is formed through the cooling of magma?

Igneous rock is formed through the cooling and solidification of magma or lava. When magma cools slowly beneath the Earth's surface, it crystallizes and forms intrusive igneous rock, commonly known as plutonic rock. In contrast, when lava cools quickly on the surface or during a volcanic eruption, it forms extrusive igneous rock, also referred to as volcanic rock. Both types of igneous rock share the common origin of magma, distinguishing them from metamorphic and sedimentary rocks, which form through different geological processes.
