Lava flow. View of steam rising as molten rock (lava) enters the sea on the coast of Big Island, Hawaii. This flow originated from the Kilauea volcano, which is one of the world's most active. Lava reaches volcanoes from the Earth's interior through faults in the crust, and is forced through them by the high pressure within the Earth. The black rock of this coastline is made from old lava flows. Lava flows like this mean that the Hawaiian islands are still increasing in size.
