How Are Granite Rocks Formed
Granite is hard igneous stone that is formed over millions of years by volcanic activity. Magma flows from volcanic activity and slowly cools over millions of years. During the process, magma combines with various minerals including hornblend, feldspar, mica and quartz to create its "crystal appearance". The elements are compressed by forces .

Gneiss is formed from the high-temperature metamorphism of existing igneous rocks, generally granite or diorite. The rocks that form gneiss are exposed to extreme pressures and temperatures of between 600 and 700 degrees Celsius. These temperatures cause the individual minerals to migrate, forming .
"Granite is a wide-spread type of intrusive igneous rock that has granular texture formed by the large and visible crystals of quartz, alkali feldspar and mica. It is formed beneath the earth's surface at depths up to 50 km by the slow cooling of magma.
