2. A hot spring is a spring that is produced by the emergence
of geothermally heated groundwater from the Earth's crust.
There are geothermal hot springs all over the Earth. One of
the most known emergencies are called Geysers

infiltrated rain water is heated by the
magma located below

7. How the hot springs form at Bath
•The water fells as rain on the
nearby Mendip Hills.
• It percolates down through
limestone aquifers to a depth of
between 2-4 km where geothermal
energy raises the water
temperature.
• Under pressure, the heated water
rises to the surface along fissures
and faults
• Hot water at a temperature of 46
°C rises here at the rate of 1 million
litres every day.
