What basic type of rock is granite. It forms from the slow crystallization of magma below earth s surface. It has been used for thousands of years and is regarded as a symbol of status strength. Granite is extremely hard and less affected by the freeze thaw cycle the forces of abrasion and the surface exfoliation processes that are all a part of physical weathering. Pink granite sample approximately 1 3cm in size large crystals in this felsic plutonic rock what is granite.
