On Earth , a geyser tends to be a hot spring of water bubbling below the surface, which occasionally boils over, sending jets metres into the air. Elsewhere in the Solar System, however, geysers can form from gases and be much more dramatic. The nitrogen geysers on Triton, Neptune's moon, reach several kilometres into the atmosphere.
a thermal spring that erupts intermittently and to different heights above the surface of the Earth; eruptions occur when water deep in the spring is heated enough to turn into steam, which forces the liquid water above it out into the air
A type of hot spring that intermittently erupts jets of hot water and steam, the result of groundwater coming into contact with rock hot enough to create steam under conditions preventing free circulation. Many of the best examples are found in Yellowstone National Park in Wyoming.
A spring from which columns of hot water gush. On land, geysers discharge steam as well as hot water into the air; deep under the ocean, pressure keeps the water from turning into steam and the discharge is into the surrounding seawater.
a type of hot spring seen on land that episodically erupts jets of hot water and steam. It results from ground water being heated by coming in contact with hot rock deep in the Earth's crust, and then rising to the surface. | | | | | | | | | | N | O | | | | | | | X | Y | Z
