What is the Water Cycle ???? … The water cycle is the path that water follows as it moves from the air to the ground and back to the air over and over again. Water never leaves the Earth. It is constantly being cycled through the atmosphere, ocean, and land. The water cycle is crucial to the existence of life on our planet and driven by energy from the sun. Water cycle it starts from heating.
Evaporation & Transpiration HOW WATER CYCLE HAPPEN ???? Condensation Precipitation Run Off
Evaporation Transpiration 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. Transpiration is the process by which plants lose water out of their leaves. Transpiration gives evaporation a bit of a hand in getting the water vapor back up into the air.
Condesation As water (in the form of gas) rises higher in the atmosphere, it starts to cool and become a liquid again. This process is called condensation. When a large amount of water vapor condenses, it results in the formation of clouds.
Precipitation 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.
Run Off When rain falls on the land, some of the water is absorbed into the ground forming pockets of water called groundwater. Most groundwater eventually returns to the ocean. Other precipitation runs directly into streams or rivers. Water that collects in rivers, streams, and oceans is called runoff.
The causes become polution on the water cycle. Don’t throw rubbish everywhere !!!
From the explanation we can to know how the process of water cycle. Start from evaporation on the seas, lakes and rivers till run off into the sea again. It happen continually. In the other hand, to mainyain the continually of the water cycle we should keep our environment by not throwing garbage or other wastes into the seas, rivers, or other places.
