Mineral-rich waters
in the Blue Lagoon,
Iceland, are said to
be beneficial to
people’s health.
ICELAND
Iceland is situated in the north Atlantic on
the Mid-Atlantic Ridge. As a result, it has at
least 20 active volcanoes and suffers frequent
earthquakes. There are numerous thermal
springs with boiling mud lakes and geysers.
Water from hot springs (above) is used to
provide hot water and heating for much of
Iceland’s population, most of whom live
on the coast. The warm Gulf Stream
ensures that the country’s ports
stay ice-free in winter.
ICEBERGS
Icebergs in the Atlantic Ocean are
formed when icesheets and glaciers
reach the sea. Parts break off and start
to drift, driven by winds and currents.

The Atlantic
covers one-fifth
of Earth’s
surface.
