Granite is igneous rock. It is widely spread within the earth`s crust and is formed through the cooling and solidification of magma within the Earth`s mantle. It is one of the hardest materials. Due to its resistance and solid features, it is utilized in construction. The Egyptians used it for making obelisks. The average density of granite is 2750 kg per m3. The word granite originates from The Latin language “granum” meaning a grain. Unlike other igneous rocks, granite has not been found on the Moon.
