Water, you have no color, no taste, no smell,
you can not describe, you enjoy,
not knowing what you are. Can not say
that is necessary for life, you life itself.
You fills us with joy,
that does not explain our feelings.
Are you coming back to us strength,
with whom we have already said goodbye.
By your grace in us once again begin
bubbling springs dried up our hearts.
(Antoine de Saint-Exupery. Terre des Hommes)

Water - the most amazing substance on Earth.
Water - a substance familiar and unusual. Famous Soviet scientist Academician Petryanov his non-fiction book about water called "the most extraordinary substance in the world." A "Interesting physiology," written by Doctor of Biological Sciences BF Sergeyev, begins with a chapter on the water - "The substance that created our planet."
Scientists are absolutely right: there is no substance in the world, is more important to us than ordinary water, and at the same time there is no other such substances, the properties of which have been so many contradictions and anomalies, as in its properties.
Nearly? our planet's surface is occupied by oceans and seas. Solid water - ice and snow - covered 20% of the land. From the water depends on the planet's climate. Geophysicists say that the Earth would have long since cooled and turned into a lifeless piece of rock, if not water. She has a very large heat capacity. Heated, it absorbs heat; cooling down, gives him. The earth absorbs water, and returns a lot of heat and thus "levels" climate. And from the cold of space prevents the Earth are water molecules, which are scattered in the atmosphere - in the clouds and in the form of vapor ... you can not do without water - this is the most important substance on Earth.
