It is not unusual to find pure water naturally, although in the laboratory can be obtained either separse reach into its constituent elements, which are hydrogen ( H ) and oxygen (O). Each molecule of water is formed by an oxygen atom and two hydrogen atoms , bonded strongly to the HOH form .

In our water planet occupy a high proportion relative to the land surface , and come in different forms :seas and oceans, which contain a high concentration of salts and even cover 71% of Earth's surface ;surface waters , which include rivers , ponds and lakes ;groundwater , also called groundwater for flow below the earth's surface.

Approximately 97 % of the planet's water is salt water in oceans and seas , only 3% of the total water is fresh water ( no salt ) and that amount just over two thirds is frozen in glaciers and ice caps in poles and high mountains.
