Extrusive igneous rock such as basalt, rhyolite, pumice, and obsidian.
Extrusive igneous rock forms from solidifying lava.
Igneous rocks are formed after a volcano erupts.

Basalt is an igneous rock that is formed after a volcano erupts.
Volcanoes produce extrusive igneous rock.
When a volcano erupts the molten cools quickly it is also known as volcano glass
No. Both basalt and rhyolite are formed from molten rock erupts from a volcano.
All three rock types could be formed in areas under the seas. Two types of rock are most likely to form on the seafloor, however. Sedimentary rock is formed on the seafloor where accumulations of sediments undergo lithification processes. Extrusive igneous rock can form on the seafloor when lava erupts on its surface.

Extrusive igneous rock.
No. Both basalt and rhyolite are formed from molten rock erupts from a volcano.
lava
The rock forms over a cooling process.
obsidian is an igneous rock, it is not formed from sediment, or a rock going under heat and pressure for the second time it is formed when a volcano erupts and it cools very quickly giving it a smooth glossy surface like glass.
Lava and rock explode out of the volcano then lava pours down the volcano covering the land then turning into rock making the volcano bigger.
A volcano rock is rock formed from ash or lava erupted from a volcano.
