When melted rock reaches Earth's surface, it is called lava. Lava can flow out of volcanoes during an eruption, cooling and solidifying to form igneous rock.
LAva
An opening in the Earth's crust where melted rock reaches the surface is called a volcano.
When melted rock reaches Earth's surface, it cools quickly and solidifies to form an extrusive igneous rock. This rapid cooling prevents large mineral crystals from forming, resulting in a fine-grained texture. Common examples include basalt and rhyolite.
magma
If it reaches the surface, it is magma or lava. If it merely intrudes into rocks already formed, it is intrusive. Such as sills and dikes.

Lava....when its under the earths crust its called magma.

Volcanoes do not cause rocks to melt, they are just the exit where melted rock come to the earths surface.
