What is a lava flow?
Flexi Says:
Lava is molten rock that reaches Earth's surface in a volcanic eruption. This may include lava, rock fragments, ash, and gases. When lava is thick, it flows slowly. If thick lava makes it to the surface, it cannot flow far from the vent. It often stays right in the middle of a crater at the top of a volcano. Here the lava creates a large, round lava dome. A lava plateau is made of a large amount of fluid lava. The lava flows over a large area and cools. This creates a large, flat surface of igneous rock.
