crater   (krā'tər)  Pronunciation Key 
  1. A bowl-shaped depression at the top of a volcano or at the mouth of a geyser. Volcanic craters can form because of magma explosions in which a large amount of lava is thrown out from a volcano, leaving a hole, or because the roof of rock over an underground magma pool collapses after the magma has flowed away.

  2. A shallow, bowl-shaped depression in a surface, formed by an explosion or by the impact of a body, such as a meteorite.
