What are five features formed by magma?

What do you call hardened magma?
The term igneous comes to us from the Latin word “Ignis” which means fire. Igneous rocks are produced this way but most igneous rocks are produced deep underground by the cooling and hardening of magma. Magma is molten (melted) rock under the surface of the Earth.
What pushes magma to the surface?
Since it is lighter than the solid rock around it, magma rises and collects in magma chambers. Eventually, some of the magma pushes through vents and fissures to the Earth’s surface. If magma is thin and runny, gases can escape easily from it. When this type of magma erupts, it flows out of the volcano.
