How does a volcano form into a mountain?
Over time the magma chamber found inside volcanos is cut off from the mantle by tectonic plate movement. Without constant exchange of hot magma from the mantel to replace the colder magma in the volcano, (convection), the magma inside the volcano hardens into igneous rock.

How can rock form when a volcano erupts?

Where does lava go when it erupts?
When lava reaches the surface, it quickly hardens into rock. The resulting rock will have either a glassy texture (with no crystals) or have a fine-grained texture (with small crystals) because the minerals have little or no time to crystallize.
If a volcano erupts what type of rock will form?
It will form extrusive igneous rock. Beyond that they exact type will vary.
When lava explodes from a volcano and cools and hardens quickly, what kind of rock does it form from?
igneus rock
What type of rock forms form magma erupts from an undersea volcano?
