If the magma cools on the surface of the crust, it is called extrusive igneous rock, such as pumice, basalt or rhyolite. If the magma cools inside the crust, it is called intrusive igneous rock, such as granite.

1. Extrusive or Volcanic Igneous Rocks.
2. Intrusive or Plutonic Igneous Rocks.

Which type of rock does magma form when it hardens?
Igneous
What does magma that is blasted into the air form when it hardens?
Extrusive igneous rock.
Magma that hardens vertically underneath the surface will form a sill?
No. A sill forms when magma hardens parallel to the rock layers, which is usually horizontal. When magam hardens vertically, it forms a dike.
How does an Igneous rock turn into Magma?
No. If it cools as magma it will form an intrusive igneous rock. To form an extrusive igenous rock it must erupt from a volcano, where it becomes lava or pyroclastic material.
