WebAt very high temperatures (over 1300°C), most magma is entirely liquid because there is too much energy for the atoms to bond together. As the temperature drops, usually because the magma is slowly moving upward, … WebApr 8, 2024 · The initial step in the crystallization process is Nucleation. The 1st atom in the mass to form a crystal structure becomes a center, and more atoms gather around the nucleus. As this process takes place, more unit cells assemble around the nucleus, and a small seed crystal is formed. WebJul 15, 2024 · This happens because when magma erupts into lava, it cools more quickly than it would if it stayed inside the earth, giving crystals less time to form.
