Yes, temperature can affect granite. Granite is a type of igneous rock that is formed through the slow crystallization of magma below the Earths surface. When exposed to high temperatures, granite can undergo thermal expansion, which can cause cracks and fractures. Additionally, prolonged exposure to extreme temperatures can cause discoloration, oxidation, and other forms of weathering on the surface of the granite. However, granite is generally known for its durability and resistance to high temperatures, making it a popular material for use in kitchen countertops, fireplaces, and other areas where heat is a concern.
