The type of igneous rock that hardens under the earths surface is called the Intrusive Igneous Rock. Intrusive Igneous Rocks are of two main types, Hypabasal and Plutonic. The plutonic forms at deeper depths.
It forms an igneous rock. If it is within the Earth, then it is an intrusive igneous rock (e.g. granite) and if it is erupted onto Earth's surface then it is an extrusive igneous rock (e.g. basalt).
intrusive igneous rock: magma cools and hardens in the earth and later forms an intrusive igneous rock. extrusive igneous rock: magma flows onto earth's surface and becomes lava. Then, lava cools and hardens above earth's surface and later forms an extrusive igneous rock.

Igneous Rock
When igneous rock forms on the Earth's surface, including on the ocean floor, it's called extrusive. It's called intrusive rock when it forms beneath Earth's surface, such as in mines.
Igneous rock. Extrusive igneous rock forms at or near the surface, intrusive igneous rock forms below the surface.
Igneous rock. Extrusive igneous rock forms at or near the surface, intrusive igneous rock forms below the surface.

If the magma has hardened before being exposed at the surface it would be considered an intrusive igneous rock. It is hardens at or near the surface, it would be called extrusive igneous rock.

Intrusive igneous rock
Extrusive igneous rock is one of two different types of igneous rocks. The other kind is intrusive igneous rock. Intrusive igneous rock is formed when magma in Earth's lithosphere cools and hardens. Extrusive igneous rock is formed when lava on Earth's surface cools and hardens.
Igneous Rock is formed when magma cools and hardens. It depends on whether it cools above ground or under ground for the size of the mineral crystals forming inside it.
