The water cycle (known scientifically as the hydrologic cycle) refers to the continuous exchange of water within the hydrosphere, between the atmosphere, soil water, surface water, groundwater, and plants.
Water moves perpetually through each of these regions in the water cycle consisting of following transfer processes:
evaporation from oceans and other water bodies into the air and transpiration from land plants and animals into air.
precipitation, from water vapor condensing from the air and falling to earth or ocean.
runoff from the land usually reaching the sea.
Most water vapor over the oceans returns to the oceans, but winds carry water vapor over land at the same rate as runoff into the sea, about 36 Tt per year. Over land, evaporation and transpiration contribute another 71 Tt per year. Precipitation, at a rate of 107 Tt per year over land, has several forms: most commonly rain, snow, and hail, with some contribution from fog and dew. Condensed water in the air may also refract sunlight to produce rainbows.
Water runoff often collects over watersheds flowing into rivers. A mathematical model used to simulate river or stream flow and calculate water quality parameters is hydrological transport model. Some of water is diverted to irrigation for agriculture. Rivers and seas offer opportunity for travel and commerce. Through erosion, runoff shapes the environment creating river valleys and deltas which provide rich soil and level ground for the establishment of population centers. A flood occurs when an area of land, usually low-lying, is covered with water. It is when a river overflows its banks or flood from the sea. A drought is an extended period of months or years when a region notes a deficiency in its water supply. This occurs when a region receives consistently below average precipitation.
That is a spectacular shot Francisco! The contrast settings here enhance the effect of this dramatic scene. Great warm colors and lovely note as well.Bravo! Powerful presentation in my opinion!
Nice to see you back MF! I hope everything ok for you and your family, including your nice son. I like the atmosphere of this sea landscape and the warm tones. I missed your wonderful insects! Warm regards,
Marvellous light on this beach, you caught it in such an artistic way. Very pleasant landscape-picture shown with perfect sharpness and nice horizontal composition!
I didn't make a WS for your previous shot, because in my mind I would have taken the picture itself from a slightly different point of view. With the bee more at right of the shot.
