How does the cyclic nature of energy work in a geyser?

Question

help! please, i dont know.

Answer 1

Geysers are a result of the right kind of hydrological and geologic combinations. Only about 1000 of them exist.

They happen when ground water seeps down into the ground until it is heated by rock that is heated by magma. The hot water rises due to convection The top of the water column cools of as it rises, presses down on the hot water underneath it creating pressure until that water boils and then erupts.

Answer 2

Geez, I hate to disagree with a typically good answerer. My understanding is that the water is heated at depth to temperatures that, if at a lower pressure, would result in boiling (higher pressure raises the boiling point). As the water rises because of buoyancy caused by its high temperature, it ascends into lower pressure zones (higher in the crust or closer to the surface), where boiling can and does occur at the temperature the water is at. The initial expansion of the first boiling lowers pressure locally (it pushes "up" on the overlying water), and this leads to even more boiling, and all that expansion from the boiling shoots the water upward very rapidly, making the geyser.

It is sort of like when you shake a bottle of soda, and then unscrew the cap.
