How do springs geysers and artesian wells form?

Springs, geysers, and artesian wells all involve the movement of groundwater. Springs occur when groundwater flows to the surface due to pressure or geological formations. Geysers form when heated groundwater builds pressure until it erupts explosively. Artesian wells arise when water from an aquifer is trapped between impermeable layers, allowing it to rise to the surface under natural pressure when accessed by drilling.
