Granite is a rock that contains the mineral quartz, the pink crystals that are known as orthoclase feldspar and the black crystals that are known as hornblende. The answer is letter C. Granite forms when magma cools slowly underground. Granite is an intrusive igneous rock and is mostly grained coarsely and light in color. It is formed by the slow cooling of magma for a long period of time and is the main reason why it has a combination of so many large crystals. Granite is composed mostly of quartz and feldspar with minor amounts of mica, amphiboles and other minerals. There are many uses of granite due to its availability on earth. Its physical properties are it resists abrasion, weathering, strong enough to bear weight and can be polished. They can be made into floor tiles, monuments for cemetery, staircases, stone pavements and building veneer.
