### Class subject: Water cycle.

 The water cycle, also known as the hydrologic cycle, is a biogeochemical cycle that 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 (salt 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. Here are 11 basic processes in the cycle of water in nature: 1. Percolation is the movement of water through the soil itself. 2. Infiltration happens when water soaks into the soil from the ground level. 3. Runoff is the water that is pulled by gravity across land's surface(rivers), replenishing surface water. 4. Transpiration is the evaporation of water through minute pores, or stomata, in the leaves of plants. 5. Precipitation is water released from clouds in the form of rain. 6. Sublimation is the process of snow and ice changing into water vapor in the air without first melting into water. 7. Deposition is the process of water vapor changes directly into ice—such a snowflakes and frost. 8. Condensation is the process by which water vapor in the air is changed into liquid water. 9. Evaporation is the process by which water changes from a liquid to a gas or vapor. 10. Transportation is water in different phases moving through the atmosphere. 11. Plant uptake is water taken from the groundwater flow and soil moisture.
