Granite is an igneous rock. Igneous rocks are formed from solidified magma or lava. Granite specifically is a plutonic rock, which means it forms deep beneath the Earth's surface when molten magma cools and solidifies slowly over a long period of time. It is composed mainly of quartz, feldspar, and mica minerals, and has a granular texture. Granite is a common type of rock that is used in construction for buildings, monuments, countertops, and other decorative applications due to its durability, strength, and attractive appearance.
