Volcano Links
Volcanoes are openings in the earth's crust that release molten rock. Hot magma is constantly rising up inside Earth's volcanoes as well as from cracks in the ocean floor. Volcanic eruptions range from quiet flows of lava to violent explosions of ash, rocks, and gas. There are active volcanoes all over the world. Planet Diary will feature the most explosive stories.
