HOW HOT SPRINGS AND GEYSERS ARE FORMED

Hot spring is a place where hot water is emitted from the ground quietly e.g. at the shores of Lakes Magadi and Bogoria.




A geyser is a jet of water and steam which are violently ejected from the ground e.g. at Olkaria and western shores of L. Bogoria.

HOW HOT SPRINGS AND GEYSERS ARE FORMED

How They Are Formed

  • Percolating water is heated by hot rocks or magma.
  • Some collect into chambers called sumps where it develops pressure causing it to be superheated super heated.
  • The pressure forces the steam outwards towards the earths surface through holes and cracks in rocks.
  • The steam comes out of the ground which reduces pressure in sumps causing the water to expand/boil and come to the surface.
  • The steam comes out with a whistling sound accompanied by water forming a geyser.
  • The escaping steam heats ground water in surrounding rock.




  • The heated water may find its way to the surface where it quietly comes out of the ground forming a hot spring
