Water at the Earth’s surface evaporates into water vapor which rises up into the sky to become part of a cloud which will float off with the winds, eventually releasing water back to Earth as precipitation .
Where does most of the water in the water cycle return to?
Most precipitation falls back into the oceans or onto land , where, due to gravity, the precipitation flows over the ground as surface runoff. A portion of runoff enters rivers in valleys in the landscape, with streamflow moving water towards the oceans.
What are the steps of the water cycle?
The water cycle consists of three major processes: evaporation, condensation, and precipitation . Evaporation is the process of a liquid’s surface changing to a gas. In the water cycle, liquid water (in the ocean, lakes, or rivers) evaporates and becomes water vapor.
What are the 5 steps to the water cycle How is water moved around the Earth?
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 in short?
The water cycle shows the continuous movement of water within the Earth and atmosphere. ... Liquid water evaporates into water vapor, condenses to form clouds, and precipitates back to earth in the form of rain and snow. Water in different phases moves through the atmosphere (transportation).

What comes first in the water cycle?
The water cycle begins with evaporation . It is a process where water at the surface turns into water vapors. Water absorbs heat energy from the sun and turns into vapors. Water bodies like the oceans, the seas, the lakes and the river bodies are the main source of evaporation.
What is 7th water cycle?
This runoff combines to form channels, rivers and ends up into lakes, seas and oceans. Here the water enters hydrosphere. Step 7: Infiltration . Some of the water that precipitates does not runoff into the rivers and is absorbed by the plants or gets evaporated. It moves deep into the soil.
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 . ... The sun, which drives the water cycle, heats water in the oceans. Some of it evaporates as vapor into the air.
What is water cycle for Class 3?
A simple science lesson and fun water cycle video for kids in 3rd, 4th and 5th grade! 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.
Who does the water cycle work?
The heat of the sun provides energy to make the water cycle work. The sun evaporates water from the oceans into water vapor. This invisible vapor rises into the atmosphere, where the air is colder. The colder air causes water vapor to condense into water droplets and clouds.
Where is water found?
Water can be broadly separated into salt water and fresh water. Salt water is 97% of all water and is found mostly in our oceans and seas . Fresh water is found in glaciers, lakes, reservoirs, ponds, rivers, streams, wetlands and even groundwater.
What happens if there is no water cycle on Earth?
The water cycle brings water to everywhere on land, and is the reason that we have rain, snow, streams, and all other kinds of precipitation. Stopping it would cause an endless drought. ... No water flow in lakes would cause overgrowth , killing many species of fish and other lake wildlife.
What is the importance of water cycle in our environment?
Why is the hydrologic cycle important? The hydrologic cycle is important because it is how water reaches plants, animals and us ! Besides providing people, animals and plants with water, it also moves things like nutrients, pathogens and sediment in and out of aquatic ecosystems.
How are clouds formed Class 6?
How are clouds formed? The process of evaporation followed by condensation causes the formation of clouds. Water present on the earth’s surface gets evaporated due to sunlight, and then rises up in the atmosphere. On reaching a certain height, water vapour present in air condenses to form tiny droplets of water.
What is meant by condensation Class 6?
Condensation is a process of changing of a substance from vapour to liquid on cooling . For example: – If we take water in a pan and if heat it the water in the pan will start boiling. So liquid form of water is changing into vapour form.
