The process of a geyser eruption.

Geyser eruptions occur when water from the surface seeps down the Earth’s crust until it hits magma heated rocks that lay below natural underground water reservoirs. A fight begins between the cooler water at the top of the vent and the water below which is now becoming superheated because of the pressure from the cooler water above. Steam rises at the geyser’s vent as the superheated water boils, causing the surface water to spill out and release pressure. With this lower pressure, the eruption develops as the boiling water and steam bursts to the surface. The reason for such a vertical eruption is because of the geyser’s tubing system. Geyserite (primarily SiO₂) is deposited in the walls of the tubes and at the surface vents from dissolved rocks, which makes the tubes carry the pressure all the way to the surface without seeping through the rocks around it.
