Hot Springs
- Ground water, coming in contact with the magma, gets heated beyond 36° C. It comes to the surface as a hot spring.
- For example – Ladakh, Manali, volcanic regions of Iceland, YellowStone National Park.
Geysers
- It is a special type of hot spring, which ejects steam and superheated water from an underground source through a hole in the ground, intermittently.
Fumaroles
- They are characterised by full-scale continuous jet-like emission of hot water from a vent.
