G is for Geyser

Geysers are jets of water that shoot out of certain places on the Earth. Warm water builds up pressure under the cool water, but the cool water holds the warm water until the warm water finds a crack and puuuuuuu! Out it shoots! It is made of a jet of hot liquid or gas that will shoot constantly from a crack in the crust of a planet or moon.
