What is water cycle with diagram?
The water cycle describes how water evaporates from the surface of the earth, rises into the atmosphere, cools and condenses into rain or snow in clouds, and falls again to the surface as precipitation.
How do water molecules change in each step of the water cycle?
There are four main stages in the water cycle. They are evaporation, condensation, precipitation and collection. Water vapour droplets join together to make clouds! Condensation: This is when water vapour in the air cools down and turns back into liquid water.
How do water molecules change in water cycle?
When water changes state in the water cycle, the total number of water particles remains the same. The changes of state include melting, sublimation, evaporation, freezing, condensation, and deposition. The water particles in each state behave as energy is absorbed or released. .
What are the 5 steps of the water cycle?
Of the many processes involved in the water cycle, the most important are evaporation, transpiration, condensation, precipitation, and runoff.
What is transpiration Ncert?
Transpiration is the evaporative loss of water by plants. It occurs mainly through the stomata in the leaves.
What are the 4 steps of the water cycle?
There are four main parts to the water cycle: Evaporation, Convection, Precipitation and Collection. Evaporation is when the sun heats up water in rivers or lakes or the ocean and turns it into vapour or steam. The water vapour or steam leaves the river, lake or ocean and goes into the air.
How does the movement of water molecules change when water goes from solid ice to liquid?
When ice is warmed above freezing, it melts and becomes liquid water. As a liquid, the attractive forces between molecules weaken and individual molecules can begin to move around each other. Because the molecules can slip and slide around one another, water takes the shape of any container it is in.
What are the strategies for water conservation?
Water conservation basically aims at matching demand and supply. The strategies for w ater conservation may be demand oriented or suppl y oriented and/or management oriented. The strategies may vary depending upon the field of water use,
What is the importance of the diagram of the water cycle?
The diagram of the water cycle is useful for both Class 9 and 10. It is one of the few important topics which are repetitively asked in the board examinations. The complete water cycle is carried into four stages which are as follows: Evaporation, Condensation, Precipitation and Collection.
What is the most important step in the direction of conservation?
The most important step in the direction of finding solutions to issues of water and environmental conservation is to change peoples’ attitude and habits. Water conservation basically aims at matching demand and supply of water [8].
What are the different methods used to preserve rainwater?
There are different methods used to preserve rainwater instead of getting it wasted. Farmers can also contribute to this system of conservation of water by using Drip irrigation system in their fields. This is a type of irrigation system which can be practised by all framers to save water.
