This category deals with one of the most destructive weather phenomena, floods. Floods can be caused by hurricanes and heavy rains. They can be in rivers, lakes, streams, even that little harmless creek up the road. Sites listed here discuss anything flood related, from specific flood incidents to the phenomenon behind floods, to how to deal with flooding before and after.
A volcano is an opening in a planet's surface which allows hot, molten rock, ash and gases to escape from below the surface. Volcanic activity involving the extrusion of rock tends to form mountains over a period of time.
