Igneous rock
Lava
Yes.
Sometimes the plates on the earths crust crash into each other, forcing one to go lower. The friction causes the rock to get hotter and hotter until it melts. This is called magma. The magma keeps getting hotter, but it needs somewhere to go, so it surges up through the earths crust, making a hole. That is how a volcano is made. Once the hole is made, magma from the earths core comes to the surface, causing the volcano to spit lava
The Igneous rock formed when magma cools are; 1. Extrusive (Volcanic) Igneous Rock; which are igneous rocks formed when magma cools outside the earths crust. The texture of of extrusive igneous rock is fine grained. 2. Intrusive (Plutonic) Igneous Rock; these are igneous rocks formed by gradual cooling of magma within the earths crust. The texture is coarse grained.
Lava....when its under the earths crust its called magma.
No. The crust is made of solid rock.
Igneous rock
It's called intrusive igneous rock.
Lava
All of the atmospheric gases can be found trapped in magma and solidified rock.
It should be magma is the hottest because it is usually molten rock that has not reached the surface during an eruption.Lava is 2nd hottest. It is the molten rock we see when a crack in the crust of the earth or a volcano eruption allows molten rock from beneath the crust to come up.
If it finds its way dowm into the earths crust through rock cycle and then is melted and mixes together to form molten magma, it could re-erupt to the earths surface and form an extrusive igneous rock or cool and solidify within the earths crust as an intrusive igneous rock.

Tectonic Plates are part of the crust, and floats on the semi-molten rock magma layer.
