What is water cycle in short?
The water cycle is the path that all water follows as it moves around Earth in different states. Water vapor—a gas—is found in Earth’s atmosphere. Water can be found all over Earth in the ocean, on land and in the atmosphere. The water cycle is the path that all water follows as it moves around our planet.
What does water cycle mean?
The water cycle shows the continuous movement of water within the Earth and atmosphere. It is a complex system that includes many different processes. Liquid water evaporates into water vapor, condenses to form clouds, and precipitates back to earth in the form of rain and snow.
What is water cycle with diagram?
It is also known as the hydrological cycle or the hydrologic cycle. During the process of the water cycle between the earth and the atmosphere, water changes into three states of matter – solid, liquid and gas. The diagram of the water cycle is useful for both Class 9 and 10.
What is water cycle for kids?
The water cycle describes the existence and movement of water on, in, and above the Earth. Earth’s water is always in movement and is always changing states, from liquid to vapor to ice and back again.
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 the weather cycle?
: periodic recurrence of some feature of the weather.
What is water cycle for Class 4?
There are four main stages in the water cycle. They are evaporation, condensation, precipitation and collection. Condensation: This is when water vapour in the air cools down and turns back into liquid water. Precipitation: This is when water (in the form of rain, snow, hail or sleet) falls from clouds in the sky.
What are the 5 stages of water cycle?
Student Features. Many processes work together to keep Earth’s water moving in a cycle. There are five processes at work in the hydrologic cycle: condensation, precipitation, infiltration, runoff, and evapotranspiration. These occur simultaneously and, except for precipitation, continuously.
What is water cycle for Class 6?
Answer: The constant flow of water from the Earth to the atmosphere and back to the Earth is known as the water cycle. The two main steps involved in water cycle are evaporation and condensation. Then, it condenses (condensation) to form tiny water droplets that further join together to form clouds.
What are the sources of water class 6?
The three main sources of water are:
- Rainwater.
- Groundwater – This includes water bodies like Wells and Springs.
- Surface water – This includes different water bodies like Sea, Oceans, Reservoirs, Rivers, Streams, Ponds, Lakes and Tanks.
What if it rains heavily Class 6?
If It Rains Heavily (1) Rains bring relief by cooling the environment after hot summer days. (2) The sowing of many crops depends on the arrival of rains during monsoon. (3) Rains provide water in the rivers and dams of hydroelectric power plants. (4) Rains fill the lakes and ponds which act as sources of water.
What is water cycle for Class 3?
WATER CYCLE DEFINITION. 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 water cycle for Class 8?
The water cycle, also known as the hydrologic cycle or the hydrological cycle, describes the continuous movement of water on, above and below the surface of the Earth. During this process, water changes its state from one phase to another, but the total number of water particles remains the same.
What grade do you learn the water cycle?
This is a science lesson for students in grade three and four on the water cycle. Through this lesson students will be able to give an accurate and detailed description of the water cycle including the process that accompany it (evaporation, condensation, and precipitation).
What is the role of air in water cycle?
Although the atmosphere may not be a great storehouse of water, it is the superhighway used to move water around the globe. Evaporation and transpiration change liquid water into vapor, which ascends into the atmosphere due to rising air currents.
What are the five uses of air?
Important Uses of Air
- Sustain life and growth.
- Combustion.
- Maintaining Temperature.
- Supplier of Energy.
- Photosynthesis.
What are the components of air?
The air in the atmosphere consists of nitrogen, oxygen, which is the life-sustaining substance for animals and humans, carbon dioxide, water vapour and small amounts of other elements (argon, neon, etc.). Higher in the atmosphere air also contains ozone, helium and hydrogen.
Is air more important than water?
Both water and air are important for our lives. Air pollution is more dangerous than water pollution, because we use air every second of our lives. People can live without water because we still can get water from other sources but people can’t live without air.
Why do we need air and water?
Air and water are the natural resources of the environment. Human beings, animals and plants need air to live. We cannot see air but can feel it.
