Description
- Earth's water cycle
- As the Earth's surface water evaporates, wind moves water in the air from the sea to the land, increasing the amount of freshwater on land.
- Water vapor is converted to clouds that bring fresh water to land in the form of rain snow and sleet

What is the first stage of the water cycle?
Stages of the water cycle. Stage 1. The first stage of the water cycle is when moisture from the sea and plants is lifted into the atmosphere. As the sun beats down it warms the oceans, rivers and lakes. This causes the water to rise into the air as water vapour. This process is known as evaporation.
What is water cycle in short class 3?
The water cycle is the process of water moving around between the air and land. Or in more scientific terms: the water cycle is the process of water evaporating and condensing on planet Earth in a continuous process.
What is the cycle of water called?
the hydrologic cycleThe 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 water cycle two answers short?
The Short Answer: The water cycle is the path that all water follows as it moves around Earth in different states. Liquid water is found in oceans, rivers, lakes—and even underground. Solid ice is found in glaciers, snow, and at the North and South Poles. Water vapor—a gas—is found in Earth's atmosphere.
What is water cycle Class 6 definition?
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 water cycle for Class 4?
Water cycle is defined as the way that water moves between being water vapor to liquid water and then back to water vapor. An example of water cycle is when water evaporates from oceans and then returns to the land in the form of rain.
What is a water cycle class 8?

Hint:The water cycle is the process of recycling the water within the ecosystem. There are different stages of the water cycle in which the whole process is carried out. The processes are evaporation, condensation, precipitation and deposition.
What is Toppr water cycle?
The water cycle or hydrological cycle is a continuous cycle where water evaporates, travels into the air and becomes part of a cloud, falls down to earth as precipitation, and then evaporates again. This repeats again and again in a never-ending cycle.
How do you write the water cycle?
ProcessesThe cycle starts when water on the surface of the Earth evaporates. ... Then, water collects as water vapour in the sky. ... Next, the water in the clouds gets cold. ... Then, the water falls from the sky as rain, snow, sleet or hail. ... The water sinks into the surface and also collects into lakes, oceans, or aquifers.
What is Ncert 7th water cycle?
When the water vapour cools down, it condenses and forms clouds. From there it may fall on the land or sea in the form of rain, snow or sleet. The process by which water continually changes its form and circulates between oceans, atmosphere and land is known as the water cycle (Fig 5.1). Our earth is like a terrarium.

Where does the water cycle begin and end?
The water cycle begins and ends in the ocean.
How is precipitation distributed?
Precipitation that falls to the Earth is distributed in four main ways: some is returned to the atmosphere by evaporation, some may be intercepted by vegetation and then evaporated from the surface of leaves, some percolates into the soil by infiltration, and the remainder flows directly as surface runoff into the sea. Some of the infiltrated precipitation may later percolate into streams as groundwater runoff. Direct measurement of runoff is made by stream gauges and plotted against time on hydrographs.

What are the processes that move water?
There are many processes involved in the movement of water. Listed below are different stages of the water cycle. 1. Evaporation. The sun is the ultimate source of energy, and it powers most of the evaporation that occurs on earth. Evaporation generally happens when water molecules at the surface of water bodies become excited and rise into the air.
What happens when water drops from the clouds?
Above 0 degrees centigrade, the vapours will condense into water droplets. However, it cannot condense without dust or other impurities. Hence, water vapours attach itself on to the particle’s surface. When enough droplets merge, it falls out of the clouds and on to the ground below. This process is called precipitation (or rainfall). In particularly cold weather or extremely low air pressure, the water droplets freeze and fall as snow or hail.
Why does water cool down?
The water vapour that accumulated in the atmosphere eventually cools down due to the low temperatures found at high altitudes. These vapours become tiny droplets of water and ice, eventually coming together to form clouds.
What happens when water evaporates?
Evaporation generally happens when water mole cules at the surface of water bodies become excited and rise into the air. These molecules with the highest kinetic energy accumulate into water vapour clouds. Evaporation usually takes place below the boiling point of water.
What is the process of forming rivers called?
Runoff. If the water from rainfall does not form aquifers, it follows gravity, often flowing down the sides of mountains and hills; eventually forming rivers. This process is called runoff. In colder regions, icecaps form when the amount of snowfall is faster than the rate of evaporation or sublimation.
How does water change state?
Water changes its state through a variety of processes from evaporation, melting and freezing, to sublimation, condensation, and deposition. All these changes require the application of energy.
What is the water cycle?
What is Water Cycle? The water cycle, also known as the hydrologic cycle, is the continuous movement of water from the earth’s surface to the atmosphere and then back to the ground. It is a continuous process. Hence, it does not have a starting or an ending point.
What happens after the last stage of the water cycle?
Post the last stage, water is again ready to be evaporated and resume stage I. This is how the water cycle has been going on for billions of years, thus bringing fresh water to people, animals and plants, helping them survive all around the earth.
What happens when water evaporates into the air?
Consequently, some water evaporates as vapour into the air. The rising air currents take the vapour up in the sky. Simultaneously, plants and trees also lose water to the atmosphere in the form of vapour which rises up in the sky.
What is the process of clouds?
As they become water laden, they develop into rain bearing clouds and fall back onto the earth’s surface by the process known as precipitation.
How much of the Earth's water is in the oceans?
Approximately 97% of the earth’s water resides in the oceans. A fraction of the other 3% is the fresh water which is frozen up into glaciers and icebergs. The same water has been circulating around the earth for the past 4 billion years! Yes, you read that right!

What is the water cycle?
(Physical Geography) the circulation of the earth's water, in which water evaporates from the sea into the atmosphere, where it condenses and falls as rain or snow, returning to the sea by rivers or returning to the atmosphere by evapotranspiration. Also called: hydrologic cycle.
What is the process by which water is circulated throughout the Earth and the atmosphere?
n. The continuous process by which water is circulated throughout the earth and the atmosphere through evaporation, condensation, precipitation, and the transpiration of plants and animals. Also called hydrologic cycle. American Heritage® Dictionary of the English Language, Fifth Edition.
How does water vapor come into the atmosphere?
Plants and animals also add water vapor to the air by transpiration. As it rises into the atmosphere, the water vapor condenses to form clouds. Rain and other forms of precipitation return water to the Earth, where it flows into bodies of water and into the ground, beginning the cycle over again. Also called hydrologic cycle.
What happens to water as it rises into the atmosphere?
As it rises into the atmosphere, the water vapor condenses to form clouds. Rain and other forms of precipitation return water to the Earth, where it flows into bodies of water and into the ground, beginning the cycle over again. Also called hydrologic cycle. The American Heritage® Student Science Dictionary, Second Edition.
