The water cycle , also known as the hydrologic cycle or the hydrological cycle , describes the continuous movement of water on, above and below the surface of the Earth. The mass of water on Earth remains fairly constant over time but the partitioning of the water into the major reservoirs of ice, fresh water , saline water and atmospheric water is variable depending on a wide range of climatic variables. The water moves from one reservoir to another, such as from river to ocean , or from the ocean to the atmosphere, by the physical processes of evaporation , condensation , precipitation , infiltration , surface runoff , and subsurface flow. In doing so, the water goes through different forms: liquid, solid ice and vapor. The water cycle involves the exchange of energy, which leads to temperature changes.

The hydrosphere includes the parts of the Earth that are mainly water, such as the oceans, ice caps, lakes and rivers.

This gigantic system, powered by energy from the Sun, is a continuous exchange of moisture between the oceans, the atmosphere, and the land. Plants take in water through their roots, then release it through small pores on the underside of their leaves. In addition, a very small portion of water vapor enters the atmosphere through sublimation, the process by which water changes directly from a solid ice or snow to a gas. The gradual shrinking of snow banks in cases when the temperature remains below freezing results from sublimation. While evaporation from the oceans is the primary vehicle for driving the surface-to-atmosphere portion of the hydrologic cycle, transpiration is also significant.

Water cycle

Earth is a truly unique in its abundance of water. - The hydrologic cycle is a conceptual model that describes the storage and movement of water between the biosphere , atmosphere , lithosphere , and the hydrosphere see Figure 8b Water on this planet can be stored in any one of the following reservoirs: atmosphere , oceans , lakes , rivers , soils , glaciers , snowfields , and groundwater.

The Fundamentals of the Water Cycle

Water travels around the planet through the water cycle. Rain falling where you live today may have been water in a distant ocean days before. And the water you see in a river or stream may have been snow on a high mountaintop. Water can be in the atmosphere, on the land, in the ocean, and even underground. It is recycled over and over through the water cycle.
