Why do some regions have hot springs and geysers?
Groundwater is heated by hot rock or magma underground and then forced back to the surface. Geysers erupt when pressure builds in a confined plumbing system.

Why do some volcanoes have hot springs and geysers nearby?
Magma heats underground water, which can circulate through cracks and emerge as hot springs or erupt as geysers. The heat source does not have to be an active lava flow at the surface.
