What organisms can thrive in hot springs?

A thermophile is an organism—a type of extremophile—that thrives at relatively high temperatures, between 41 and 122 °C (106 and 252 °F). Many thermophiles are archaea. Thermophilic eubacteria are suggested to have been among the earliest bacteria.

Keeping this in view, where do hot springs get their heat?

The water issuing from a hot spring is heated by geothermal heat, essentially heat from the Earth's interior. In general, the temperature of rocks within the Earth increases with depth. The rate of temperature increase with depth is known as the “geothermal gradient”.

What are the characteristics of extremophiles?

Characteristics of extremophiles. Extremophiles are organisms that live in extreme conditions of temperature, acidity, salinity, pressure, or toxin concentration. Most extremophiles are single-celled micro-organisms belonging to two domains of life – bacteria and archaea.

Are Hot Springs an indicator of volcanic activity?

Hot spring. Most hot springs discharge groundwater that is heated by shallow intrusions of magma (molten rock) in volcanic areas. Some thermal springs, however, are not related to volcanic activity.
