A geyser is a hot spring that intermittently erupts jets of steam and hot water into the air. Geysers are powered by the geothermal heat from the Earth’s interior and are typically found in volcanic regions. They are significant in studying geothermal activity, volcanic processes, and the dynamics of hydrothermal systems.
