What is water cycle definition for Class 6?
The constant movement of water from the Earth to the atmosphere and back to the Earth through the process of evaporation, condensation and precipitation is known as the water cycle.
What is the importance of water cycle for Class 6?
Water cycle is important because of the following reasons: (1) Water cycle makes fresh water available in the form of rain: The sea-water is highly salty which is not fit for drinking by animals or for the growth of plants. But the rain water is pure water. It can be utilised by animals as well as plants.
Why is the water important for us?
Your body uses water in all its cells, organs, and tissues to help regulate temperature and maintain other bodily functions. Because your body loses water through breathing, sweating, and digestion, it’s important to rehydrate by drinking fluids and eating foods that contain water.
What does water cycle stand for?
Water cycle. The water cycle, also known as the hydrologic cycle or the H2O cycle, describes the continuous movement of water on, above and below the surface of the Earth. Although the balance of water on Earth remains fairly constant over time, individual water molecules can come and go, in and out of the atmosphere.
What are the steps in water cycle?
The steps in the water cycle are evaporation, condensation, precipitation and runoff. Transpiration is an additional element in the water cycle. Evaporation is the process by which water on the surface changes from a liquid to a gas state, water vapor.
What is the defining characteristic of a water cycle?
Water Cycle. the continuous migration of water on earth (in its atmosphere, hydrosphere , and crust), accompanied by phase transitions of the water and possessing a more or less pronounced cyclical character. The water cycle consists of the evaporation of water from the underlying surface and its transport by air currents from the evaporation site,…
What depends on the water cycle?
The Water Hydrologic Cycle . All life depends on water and in its absence life ceases. The kind of vegetation present at a site depends upon the amount of free water available and a principal factor in terrestrial net primary production is the amount of precipitation a site receives.
