Why water cycle is called cycle?
Why is water cycle called a cycle? The water cycle, also known as the hydrologic cycle, describes the continuous movement of water as it makes a circuit from the oceans to the atmosphere to the Earth and on again. Most of Earth’s water is in the oceans. The sun, which drives the water cycle, heats water in the oceans. What is Ncert 7th water cycle?
Why is water used in the water cycle?
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.
The Water Cycle Helps to Regulate the Earth’s Temperature.

What are the 7 cycles of water?
A fundamental characteristic of the hydrologic cycle is that it has no beginning an it has no end. It can be studied by starting at any of the following processes: evaporation, condensation, precipitation, interception, infiltration, percolation, transpiration, runoff, and storage.
How does the water cycle work facts?
How does the water cycle work? The water cycle works by using the energy of the sun to exchange water from the surface of the earth to the atmosphere and back again in a continuous cycle, whether liquid, solid or gas. It’s always happening, all around us, all the time.
Where does the water cycle end?
The water cycle begins and ends in the ocean. Evaporation, one of the major processes in the cycle, is the transfer of water from the surface of the Earth to the atmosphere. By evaporation, water in the liquid state is transferred to the gaseous, or vapour, state.
How old is the water cycle?
about 3.8 billion years ago
It joins the Earth’s oceans, land, and atmosphere. The Earth’s water cycle began about 3.8 billion years ago when rain fell on a cooling Earth, forming the oceans. The rain came from water vapor that escaped the magma in the Earth’s molten core into the atmosphere.
