Two types of igneous rock are intrusive (also called plutonic) and extrusive. There is also porphyry rock which is partly intrusive and partly extrusive. Porphyry rock has large crystals embedded in a mass of much smaller crystals. The large crystals formed underground as does intrusive rock, and were carried in lava when it erupted. The mass of smaller crystals formed around the large crystals when the lava cooled quickly above ground, as does extrusive rock.

What is igneous rock?
Igneous rock is a type of rock that forms from the cooling and solidification of magma or lava. It can be classified into two main types: intrusive (plutonic) igneous rock, which forms beneath the surface, and extrusive (volcanic) igneous rock, which forms on the surface. Examples include granite, basalt, and pumice.
What type of igneous rock hardens under the surface?
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.
