What are the 5 major processes of the water cycle?
These occur simultaneously and, except for precipitation, continuously. Together, these five processes - condensation, precipitation, infiltration, runoff, and evapotranspiration- make up the Hydrologic Cycle. Water vapor condenses to form clouds, which result in precipitation when the conditions are suitable.
What are the 7 processes of the water cycle?
The water cycle processes involve evaporation, condensation, precipitation, interception, infiltration, percolation, transpiration, runoff, and storage. What is this? Evaporation takes place when water changes from its liquid state to vapor or gaseous state.
What is a water cycle 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.
Why are water cycle processes important?
The water cycle is an extremely important process because it enables the availability of water for all living organisms and regulates weather patterns on our planet. If water didn't naturally recycle itself, we would run out of clean water, which is essential to life.
What is water cycle for Class 3?
Solar energy drives evaporation of water from the ocean. The evaporated water changes from a liquid form into water vapor a gaseous form. Evaporated water is warmed and rises into the air where it eventually cools and condenses to form clouds. With enough condensed water, you get rain!
What is the water cycle for kids?
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 10th water cycle?
The water cycle, also known as the hydrologic or hydrological cycle, is the continuous movement of water on, above, and beneath the Earth's surface. Water changes state from one phase to another during this process, but the total number of water particles remains constant.
What does water cycle Class 9 mean?

Infiltration is the last stage of the water cycle. In it, the rainwater absorbs into the ground, via soil and underlying rock layers.
What is the water cycle?
About 75 percent of our planet is covered by water or ice. The water cycle is the endless process that connects all of that water. It joins the Earth’s oceans, land, and atmosphere.
How did the Earth's water cycle begin?
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.
What is the process by which water vapor becomes liquid?
condensation. Noun. process by which water vapor becomes liquid. evaporation. Noun. process by which liquid water becomes water vapor. sublimation. Noun. the process by which snow or ice becomes water vapor without first melting and passing through the liquid phase.
How does water vapor form?
When warmed by the sun, water on the surface of oceans and freshwater bodies evaporates, forming a vapor. Water vapor rises into the atmosphere, where it condenses, forming clouds. It then falls back to the ground as precipitation. Moisture can also enter the atmosphere directly from ice or snow. In a process called sublimation, solid water, such as ice or snow, can transform directly into water vapor without first becoming a liquid.
What happens when water vapor returns to the surface?
Most precipitation lands in the oceans. Precipitation that falls onto land flows into rivers, streams, and lakes.
How does moisture enter the atmosphere?
Moisture can also enter the atmosphere directly from ice or snow. In a process called sublimation, solid water, such as ice or snow, can transform directly into water vapor without first becoming a liquid. A misty cloud rises over Deer Streams National Park.
Where is water stored on Earth?
About 1.7 percent of Earth’s water is stored in polar ice caps and glaciers. Rivers, lakes, and soil hold approximately 1.7 percent. A tiny fraction—just 0.001 percent—exists in the Earth’s atmosphere as water vapor.
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 are the three states of water?
Water goes through all the three states, solid-liquid-gas, in the process. There are several factors that assist the water cycle, the sun, air currents to name a few. The stages involved in a complete water cycle are:
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 stage 4 precipitation?
This may occur in the form of rain, hail, snow or sleet depending upon the temperature conditions. Stage IV: Runoff and Infiltration The precipitation either runs off into oceans, rivers and ground surface or is absorbed into the soil (infiltration).
What are the three major processes of the water cycle?
The water cycle consists of three major processes: evaporation, condensation, and precipitation.
What is the water cycle?
The water cycle describes how water is exchanged (cycled) through Earth's land, ocean, and atmosphere. Water always exists in all three places, and in many forms—as lakes and rivers, glaciers and ice sheets, oceans and seas, underground aquifers, and vapor in the air and clouds.
What is the process of a gas changing to a liquid?
Condensation is the process of a gas changing to a liquid. In the water cycle, water vapor in the atmosphere condenses and becomes liquid. Condensation can happen high in the atmosphere or at ground level. Clouds form as water vapor condenses, or becomes more concentrated (dense).
How does the water cycle affect the Earth's physical features?
The water cycle also influences the physical geography of the Earth. Glacial melt and erosion caused by water are two of the ways the water cycle helps create Earth's physical features.
What is the process of water evaporation?
The water cycle's evaporation process is driven by the sun. As the sun interacts with liquid water on the surface of the ocean, the water becomes an invisible gas (water vapor). Evaporation is also influenced by wind , temperature, and the density of the body of water.
How were the Great Lakes created?
The Great Lakes were created as an enormous ice sheet melted and retreated , leaving liquid pools. The process of erosion and the movement of runoff also create varied landscapes across the Earth's surface. Erosion is the process by which earth is worn away by liquid water, wind, or ice.
How does water affect the environment?
As water evaporates, for example, it absorbs energy and cools the local environment. As water condenses, it releases energy and warms the local environment.
What is the water cycle?
Water cycle, also called hydrologic cycle, cycle that involves the continuous circulation of water in the Earth - atmosphere system. Of the many processes involved in the water cycle, the most important are evaporation, transpiration, condensation, precipitation, and runoff. Although the total amount of water within the cycle remains essentially ...
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.
Why does condensation occur?
This condition occurs as the consequence of either cooling or the mixing of air masses of different temperatures.
How is water transferred in the hydrologic cycle?

The idea that the waters of Earth undergo cyclical motions, changing from seawater to vapour to precipitation and then flowing back to the... A brief treatment of the water cycle follows.
What is the primary form of atmospheric moisture?
Water vapour is the primary form of atmospheric moisture. Although its storage in the atmosphere is comparatively small, water vapour is extremely important in forming the moisture supply for dew, frost, fog, clouds, and precipitation.
What is the process of evaporation?
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. This transfer occurs when some molecules in a water mass have attained sufficient kinetic energy to eject themselves from ...
How does the water cycle start?
The water cycle starts with evaporation. It is a process where water at the surface turns into water vapours. Water absorbs heat energy from the sun and turns into vapours. Water bodies like the oceans, the seas, the lakes and the river bodies are the main source of evaporation. Through evaporation, water moves from hydrosphere to atmosphere. As water evaporates it reduces the temperature of the bodies.
How does water enter the biosphere?
As water precipitates, some of it is absorbed by the soil. This water enters into the process of transpiration. Transpiration is a process similar to evaporation where liquid water is turned into water vapor by the plants. The roots of the plants absorb the water and push it toward leaves where it is used for photosynthesis. The extra water is moved out of leaves through stomata (very tiny openings on leaves) as water vapor. Thus water enters the biosphere and exits into gaseous phase.
What happens to water droplets at high altitudes?
At high altitudes the temperature is low and hence the droplets lose their heat energy. These water droplets fall down as rain. If the temperature is very low (below 0 degrees), the water droplets fall as snow. Water also precipices in the form of drizzle, sleet and hail.
Why do clouds form at high altitudes?
At high altitudes the water vapours changes into very tiny particles of ice /water droplets because the temperature at high altitudes is low. This process is called condensation. These particles come close together and form clouds and fogs in the sky.
How does sublimation affect water vapor?
This phenomenon accelerates when the temperature is low or pressure is high.
Why do clouds pour down?
4: Precipitation. The clouds (condensed water vapors) then pour down as precipitation due to wind or temperature change. This occurs because the water droplets combine to make bigger droplets. Also when the air cannot hold any more water, it precipitates.
What happens when water pours down?
As the water pours down (in whatever form), it leads to runoff. Runoff is the process where water runs over the surface of earth. When the snow melts into water it also leads to runoff. As water runs over the ground it displaces the top soil with it and moves the minerals along with the stream.
