Igneous rocks do form on the earths surface. A volcano erupts and the lava that comes out cools and hardens forming igneous rocks.
When magma comes up to Earth's surface and hardens, it is called lava.
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.
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.
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.
