Water Cycle

Water Cycle

• The water cycle is the processes by which water circulates between the earth's ocean, atmosphere, and land, involving precipitation as rain, snow, drainage in streams and rivers, and return to the atmosphere by evaporation and transpiration.

Evaporation

• Evaporation is vaporization of a liquid and occurs from the surface of a liquid in to a gaseous(of relating to or having the characteristics of a gas)phase that is not saturated with the evaporating substance.
• The other type of vaporization is boiling, which is characterized by bubbles of saturated vapor forming in the liquid phase.

Transpiration

• Transpiration is the process by which moisture is carried through plants from roots to small pores underside of leaves, where it changes vapor and is released to the atmosphere. Transpiration is essentially evaporation of water to plant to leaves.

Condensation

• Condensation is the change of water from its gaseous form (water vapor) into liquid water.Condensation generally occurs in the atmosphere, when warm air rises, cools and looses its capacity to hold water vapor.
• As a result, excess water vapor condenses to form cloud droplets.

Precipition

• Precipitation is rain, snow, sleet, and hail. When precipitation happens all the types of it(rain ,snow,sleet ,and hail)fall to the ground

Collection

• Collection is when water falls back to the Earth it may fall into lakes, rivers, ponds, ocean.

Run-Off

• Run-off (also known as overland flow) is the flow of water that occurs when excess storm water, melt water, or other sources flows over earth's surface.
• This might occur because soil is saturated to full capacity, because rain arrives more quickly then soil can absorbs it or because impervious(roofs and pavement) send their run-off to surrounding soil that can not absorb all of it.

Nothing New

• None of the water that we have is new.All of the water that we drink has been drank by the dinosaurs even the toilet water.
