Granite is a hard, coarse-grained igneous rock composed mainly of quartz, feldspar, and mica. It forms from the slow cooling of magma deep within the Earth's crust, giving it a strong, durable structure. Granite is known for its speckled appearance and comes in a variety of colors, including white, gray, pink, and black. Due to its strength and resistance to weathering, it is widely used in construction, countertops, and monuments. Its natural beauty and durability make it a popular choice for both functional and decorative purposes.
