lava
Other forms: lavas
Is lava flowing through your street? Then you'd better run! Lava is the hot liquid rock that pours from an erupting volcano.
Under the earth's crust is molten rock called magma, along with explosive gases. Under the right conditions, the gases send the magma up through volcanoes, which act as vents in the surface of the earth. When magma reaches the surface, it becomes lava. Over time, the hot molten lava cools and becomes very hard; layers of lava eventually form mountains.
