Igneous rock
Completely molten rock would not contain any crystals. Most magmas, however, are a mixture of molten and solid crystals of some sort. It is possible that a magma could contain larger crystals of a specific mineral.
An example of a rock formed by molten material cooling is basalt. Basalt is an igneous rock that typically forms from the cooling of lava at or near the Earth's surface, such as in volcanic eruptions. It has a fine-grained texture and is commonly found in oceanic crust and volcanic islands.
Molten rock is formed through the melting of rocks in the Earth's mantle or crust due to high temperatures and pressure. When the molten rock cools and solidifies, it creates igneous rock, which can be further classified into types such as basalt, granite, and obsidian, depending on the cooling process and composition of the molten rock.
Igneous rock is produced by the cooling and solidification of molten rock. This process can occur both beneath the Earth's surface, forming intrusive igneous rocks, and at the surface, forming extrusive igneous rocks.
Cooling rate of molten rock
A rock is considered igneous if it formed directly from the cooling of molten rock.

Magma is molten rock. It becomes rock by cooling and hardening.
No. The molten rock which once constituted the moon was long ago solidified from cooling into igneous rock.
Yes, slow cooling of molten rock typically leads to the formation of large crystals. This is because slower cooling allows more time for the atoms in the molten rock to arrange themselves into a more ordered and stable crystal lattice structure. The slower the cooling process, the larger the crystals that can form.
No. Igneous rock forms from the cooling of molten material.

Igneous rock is formed by magma (molten rock) cooling and becoming solid.

Completely molten rock would not contain any crystals. Most magmas, however, are a mixture of molten and solid crystals of some sort. It is possible that a magma could contain larger crystals of a specific mineral.
The size of the crystals is a function of the rate of cooling of the molten rock. The faster the molten rock cools, the smaller the crystals will be.
