Igneous rocks
When molten material from beneath Earth's surface cools and hardens, it forms igneous rocks. Igneous rocks can be either intrusive (formed underground) or extrusive (formed on the surface), depending on where the cooling and hardening process occurs.
The substance that cools beneath the earths surface when an intrusive igneous rock forms is Magma. Magma is a molten material made up of rocks and minerals.
Igneous rock.
Magma is molten rock beneath the Earth's surface, while lava is molten rock that flows onto the surface during a volcanic eruption. When magma cools and solidifies underground, it forms intrusive igneous rocks, such as granite. When lava cools and solidifies on the surface, it forms extrusive igneous rocks, such as basalt.
Rocks that are produced when magma or lava cools and hardens are called Igneous rocks.

Igneous rock is what forms when magma cools and hardens.

When melted rock cools and hardens in or under the Earth's surface, it forms igneous rock. This process can happen above ground, forming volcanic rocks, or below ground, forming intrusive rocks.
Rocks that are produced when magma or lava cools and hardens are called Igneous rocks.
Rocks are formed when magma cools and solidifies either beneath the Earth's surface (intrusive igneous rocks) or on the surface (extrusive igneous rocks). As the molten magma cools, it crystallizes and hardens into solid rocks like granite or basalt.
Rocks that are produced when magma or lava cools and hardens are called Igneous rocks.
When molten material from beneath the Earth's surface cools but doesn't harden, it forms a type of rock called volcanic glass, or obsidian. Obsidian is a black, glassy rock formed from rapidly cooled lava, which prevents the growth of mineral crystals typically found in other types of rock.
