Hydrogen and oxygen – consists of two water molecules. Each molecule of hydrogen, oxygen consists of two component parts. Most of the seawater, and held the Earth and Earth’s oceans for 70% of the surface. The remainder of the polar ice caps, rivers, lakes, reservoirs, clouds, sea ice is locked in aquifers and groundwater. As water containing salt, drink, put the other main source of fresh, is people need to drink.
Water continues to move into what is called the water cycle. Basically, the water evaporates in the sun, forming a vapor cloud finally established. When the cloud, only to restart the process fluid does not have rain, you can fall back to Earth. Water balance on this planet will remain approximately constant in a single molecule of air in and out, move around. Moving from one location to another tank, solids liquids and gases through the various stages.
Evaporation, condensation, precipitation, infiltration, surface runoff and subsurface runoff: There are several processes involved in the hydrological cycle. Solar power evaporates the water cycle. Evaporation of water energy, environment, and then cooled. Liquid water into a gas, rises into the atmosphere. Atmosphere, when the particles collide and grow to form clouds. This is a condensation of the gas into a liquid again.
Rainfall rain scientific name. Its land, sea and fresh water falls. In addition, snow or hail may fall. It fell to the ground breaking intrusion of water into the soil and ground water supplies. Water flows beneath the surface and find its way into rivers and oceans. Groundwater runoff underground. Other water falls to the ground to escape into the river – this is the surface runoff. Then enter the river or sea, will re-evaporation. The water comes from many places on the planet, and certainly there are plenty of places to visit than you think, because of the water cycle.
