Geysers are hot springs that intermittently eject water and steam into the air due to geothermal activity beneath the Earth's surface. This natural phenomenon occurs when groundwater is heated by geothermal energy, usually from magma, and pressure builds up until it erupts, releasing hot water and steam. Understanding geysers is crucial as they provide insights into geothermal gradients and heat flow, which are vital for assessing geothermal resources and the Earth's thermal structure.
congrats on reading the definition of Geysers. now let's actually learn it.
