Granite often forms rounded hills scattered over a hillside, and is major component of the mountain ranges of the world. According to the 2010 census, the population is 116. Tens of kilometers inside the Earth, the pressure and friction produced in a subduction zone melt large quantities of rock. Granite is produced in volcanic arcs, and more commonly in mountain building resulting from the collision of two continental masses. Granite is a course-grained intrusive igneous rock formed by the crystal arrangements of quartz, feldspar, mica, and traces of other minerals. [1][2] It is formed from hot, molten magma. In India, many structures and life-size animal statues were carved using granite stones. From this theory, it is thought that the parent rock present at the time of the Earth’s formation gave rise not only to igneous rocks, but sedimentary and metamorphic rocks, as well.

It forms from magma with a high content of silica and alkali metal oxides that slowly solidifies underground. On the evolution of minerals. Granite is an intrusive igneous rock, which means it was formed in place during the cooling of molten rock. The process generates enough pressure and melting points to create granite.
