Melting: Granite forms from the melting of pre-existing rocks, such as sedimentary or metamorphic rocks, that are subjected to high temperatures and pressures deep within the Earth's crust.
Magma formation: When these rocks melt, they form a molten material called magma, which is less dense than the surrounding rocks and rises towards the Earth's surface.
Crystallization: As the magma cools and solidifies, it forms large mineral crystals that interlock with each other to form the characteristic coarse-grained texture of granite.
