Why do igneous rocks formed below Earth's surface generally have larger crystals?
Why do igneous rocks formed below Earth's surface generally have larger crystals?
- Magma contains more gas, resulting in larger crystal growth
- Magma cools down slowly, allowing time for the formation of larger crystals (correct)
- Magma cools rapidly, promoting the formation of larger crystals
- Magma has more impurities, leading to larger crystal formation
