A geyser is a type of hot spring that
ejects a column of hot and steam into the air. The
name comes from the island verb also “gjósa" which means
"emanate".
The activity of the geysers is
caused by contact between surface water and rocks heated by magma located below
the ground. The heated water returns to the heat of the
earth surface by convection through porous and fractured rocks. As
the geyser is full, the water becomes more shallow be
cold. The cold water from the surface pressed under hot, causing
the water reservoir is heat, keeping the liquid at
temperatures above its boiling point. Finally, the temperature of
the bottom of the geyser begins to rise reaching boiling point. The steam bubbles rise to
the tip of the duct. The heat water is mixing with the overheat steam sent
off violently by the column. The resulting foam between the steam and hot is
expelled out of the geyser. The water from the geyser will cooling and the
eruption ends. Most geysers form in places where there
are volcanic rocks such as riolita, which dissolves in hot water and
forms mineral deposits called clusters silíceous or geiserits. With time, these deposits strongly consolidated rock,
reinforcing the walls of the channel and allowing them to persist geyser. The
geysers are a phenomeno quite fragile condition and
whether any changes in their environment may disappear. One
of the most amazing thing is that these phenomena are
that they aren't unique on Earth. In Luna, Neptune and Triton, observed that
eruptions in nitrogen geysers.

Hi,
Are there any geysers in Spain? and in Galicia?
Are they just tourist places or have they got other functions?
Thanks.
There aren't geysers in Spain, but there is great geothermal activity in Galicia, for examlpe in Ourense. This energy is used for example for heating.
Ok, thanks
