the wonderful water cycle

The earth has a limited amount of water. That water keeps going around and around and around and around and (well, you get the idea) in what we call the "Water Cycle".

Evaporation is when the sun heats up water in rivers or lakes or the ocean and turns it into vapor or steam. The water vapor or steam leaves the river, lake or ocean and goes into the air.

Condensation:is when Water vapor in the air gets cold and changes back into liquid, forming clouds. This is called condensation.

Precipitation occurs when so much water has condensed that the air cannot hold it anymore. The clouds get heavy and water falls back to the earth in the form of rain, hail, sleet or snow.

Transpiration: As water precipitates, some of it is absorbed by the soil. This water enters into the process of transpiration. Transpiration is a process similar to evaporation where liquid water is turned into water vapor by the plants. The roots of the plants absorb the water and push it toward leaves where it is used for photosynthesis. The extra water is moved out of leaves through stomata (very tiny openings on leaves) as water vapor. Thus water enters the biosphere and exits into gaseous phase.

Runoff: As the water pours down (in whatever form), it leads to runoff. Runoff is the process where water runs over the surface of earth. When the snow melts into water it also leads to runoff. As water runs over the ground it displaces the top soil with it and moves the minerals along with the stream. This runoff combines to form channels and then rivers and ends up into lakes, seas and oceans. Here the water enters hydrosphere.

When rain or snow falls onto the earth, it just doesn't sit there, it starts moving according to the laws of gravity. A portion of the precipitation seeps into the ground to replenish Earth's groundwater. Most of it flows downhill as runoff. Runoff is extremely important in that not only does it keep rivers and lakes full of water.

what life would be like without water? the things in the earth would be dry and when we need water there isn't any. like when we wash clothes and need drinking water and water to take a bath.the lakes and the rivers and oceans

we can conserve. by Never putting water down the drain when there may be another use for it such as watering a plant or garden, or cleaning.Verify that your home is leak-free, because many homes have hidden water leaks.Repair dripping faucets by replacing washers.
