The returning water falls directly back into the oceans, or onto land as snow or rain. … The water may be taken up by plants and returned to the atmosphere through
processes like transpiration and photosynthesis
. Water may also be returned to the atmosphere through the combustion of plants in fossil fuel.
What process puts water back into the atmosphere?
Water at the surface of the ocean, rivers, and lakes can become water vapor and move into the atmosphere with a little added energy from the Sun through a process called
evaporation
. … And water vapor gets into the atmosphere from plants by a process called transpiration.
Which process of water cycle returns water vapor directly to the atmosphere?
Water at the surface of the ocean, rivers, and lakes can become water vapor and move into the atmosphere with a little added energy from the Sun through a process called evaporation. … And water vapor gets into the atmosphere from plants by a process called
transpiration
.
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).
How long does water vapor stay in the atmosphere?
Water vapour will generally stay in the atmosphere
for days
(before precipitating out) while other greenhouse gases, such as carbon dioxide or methane, will stay in the atmosphere for a much longer period of time (ranging from years to centuries) thus contributing to warming for an extended period of time.
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.

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.
How long does no2 stay in the atmosphere?
Nitrous oxide molecules stay in the atmosphere for an
average of 114 years
before being removed by a sink or destroyed through chemical reactions.
Is water vapor bad for the environment?
Water vapor is the most important greenhouse gas. It
controls the Earth's temperature
.” It's true that water vapor is the largest contributor to the Earth's greenhouse effect. On average, it probably accounts for about 60% of the warming effect.
How long does it take for carbon dioxide to leave the atmosphere?
Once it's added to the atmosphere, it hangs around, for a long time:
between 300 to 1,000 years
. Thus, as humans change the atmosphere by emitting carbon dioxide, those changes will endure on the timescale of many human lives.
How are clouds formed Class 6?
How are clouds formed?
The process of evaporation followed by condensation causes
the formation of clouds. … On reaching a certain height, water vapour present in air condenses to form tiny droplets of water. These water droplets collect to form clouds that float in air.
What is evaporation point?
Energy is used to break the bonds that hold water molecules together, which is why water easily evaporates at the boiling point (
212° F, 100° C
) but evaporates much more slowly at the freezing point. Net evaporation occurs when the rate of evaporation exceeds the rate of condensation.
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.
How do you make a water cycle?
- Put the bowl in a sunny place outside.
- Using the pitcher or bucket, pour water into the bowl until it is about 1⁄4
- Place the mug in the center of the bowl. …
- Cover the top of the bowl tightly with the plastic wrap.
- Tie the string around the bowl to hold the plastic wrap in place.
- Watch the bowl to see what happens.
How do you explain the water cycle to students?
The water cycle describes how
water evaporates from the surface of the earth
, rises into the atmosphere, cools and condenses into rain or snow in clouds, and falls again to the surface as precipitation.
