Granite is a hard, igneous rock that forms from the slow crystallization of magma beneath the Earth's surface. It is composed mainly of quartz, feldspar, and mica, giving it a speckled appearance. This durable stone is commonly used in construction and for decorative purposes, such as countertops and monuments. Its strength and resistance to weathering make it a popular choice for both indoor and outdoor applications. Many famous landmarks, like the Yosemite National Park cliffs and the Washington Monument, are made of granite. The rock comes in various colors, including gray, pink, and white, depending on its mineral composition. Granite's beauty and resilience have made it a favorite among architects and designers.
