Thermal springs

This post is also available in: deDeutsch

The upper end of the temperature scale is also inhabited by living organisms. Thermal springs are springs from which warm or hot water escapes. In many thermal springs sulphur is found more often, which sometimes gives them a nice colour and serves as an energy source for many adapted creatures, such as bacteria, algae and archaea.

 

Explanation for children: Thermal springs are water sources, but the water is hot and not cold. Often thermal springs look colorful, this comes from the sulfur that sometimes occurs there. Bacteria, algae and archaea live in thermal springs.
