WebbWhen Lava/Magma cools, it either forms large or small crystals. This depends on the time it's cooled in. When Magma cools, it cools slowly because it's hotter underneath the Earths crust, so it produces larger … WebbWhen magma cools, crystals form because the solution is super-saturated with respect to some minerals. If the magma cools quickly, the crystals do not have much time to form, so they are very small. If the magma cools slowly, then the crystals have enough time to grow and become large.

WebbIf magma cools slowly, deep within the crust, the resulting rock is called intrusive or plutonic. The slow cooling process allows crystals to grow large, giving the intrusive igneous rock a coarse-grained or phaneritic texture. The individual crystals in phaneritic texture are readily visible to the unaided eye. WebbIf the magma cools quickly, the crystals do not have much time to form, so they are very small. If the magma cools slowly, then the crystals have enough time to grow and become large. Some granites contain minerals which are up to one meter (3 ft) across!

The rate at which the magma cools determines the kind of igneous rocks that are formed. Faster cooling surface lava creates rock that is fine grained or aphanitic. The rapid cooling doesn’t allow large crystals to form. Webb7 juli 2024 · When magma solidifies below the surface of earth How are formed? 2) Intrusive: magma cools under the Earth’s surface.
