Cooling and Crystallization
Igneous rocks are the result of cooling and crystallizing magma. Igneous crystals are formed when freely moving atoms in melted rock become arranged in orderly patterns as they cool. As melted rock cools, the heat energy that allows atoms to move past one another decreases, and the natural attraction between atoms causes them to stick together with similar atoms in a crystalline structure. This process takes a long time to grow big enough to be seen.
Melting
When rocks reach extreme temperatures, they begin to melt forming magma. Magma is a molten rock made from other melted rock.
