Properties of water from a glacier and geyser

Water has three phases: liquid, gas, and solids. Can be easily changed to phase in the temperature range that is in the earth's surface. Global water cycle is based on three phases of water.

Water in the solid phase (ice) is lighter than the liquid phase. This is an anomaly; in general, other compounds in the solid phase has a density greater than the liquid phase so that it will sink. The implication: If the ice is heavier than water, so we just have sedikiit sea! The water in the polar regions of seasonal frozen, but the ice sheets will melt during the summer, or to shift to a more warm and melted there. If ice were heavier than water, it will sink to the bottom of the ocean and isolated from the hot sun. Thus, most of the ocean would be composed of a layer of ice underneath, just a few meters from the surface which is a layer of water during the summer. Furthermore, it would be very limiting evaporation and cloud formation, which is a source of fresh water on land.

Water can dissolve the salt and gas but can be easily separated as a pure vapor. The sun's rays evaporate water from the ocean, but the salts remain in the sea. The result: water vapor (clouds) driven wind toward land, then condenses into rain, which is a source of fresh water on land, then back again to the sea.

Water easily dissolves CO2 and become effective acid solution. In addition to the atmosphere, the CO2 source is also present in the root zone of the soil. All rock will undergo interaction with acid water is and will be eroded and transported to the sea.

Water that has a low viscosity and not sticky. As a result: (1) to flow as surface water water efficiently. (2) Can penetrate (infiltration) into the ground. (3) Flow through permeable rocks.

Water weighs enough to be moved by the force of gravity. As a result: allowing the flow of groundwater and surface water runoff.

Water has a density that is appropriate. The result: no water vapor out of the Earth.

Water and water vapor through. As a result: sunlight can enter thr ough the air and through tens of meters of depth of the sea and lakes, as energy requirements of life.

Water including greenhouse gases. As a result: maintaining water balance in the Earth's temperature.
