THE AIR AND THE WATER CYCLE.
The atmosphere is the superhighway in the sky that moves water everywhere over the Earth. 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.
How does air movement affect the water cycle?
The speed at which air flows over the surface of water affects the rate at which the water evaporates. As the wind blows, it sweeps away airborne water particles that are in the air. The humidity of the air in the region of this evaporation is reduced, which allows more water molecules to dissipate into the air.Mar 13, 2018
How does wind affect the water cycle?
As Earth's water evaporates, winds move water vapor from the sea to the land, increasing the amount of fresh water on land. Wind and evaporation patterns from the first animation are shown here on a map of the world. ... The ocean loses water to the air when the water evaporates and turns into water vapor (steam).

How do you explain the water cycle?
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 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 factors influence water flow?
The velocity of a river is determined by many factors, including the shape of its channel, the gradient of the slope that the river moves along, the volume of water that the river carries and the amount of friction caused by rough edges within the riverbed.Apr 20, 2018
Why is wind important?
Wind is a major factor in determining weather and climate. Wind carries heat, moisture, pollutants, and pollen to new areas. ... Warm air above the land rises, and cooler air above the water moves in over the land, creating an inland breeze. Coastal communities are usually much cooler than their inland neighbors.Nov 15, 2012
What happens at the end of a water cycle?
Most precipitation falls back into the oceans or onto land, where, due to gravity, the precipitation flows over the ground as surface runoff. ... Over time, though, all of this water keeps moving, some to reenter the ocean, where the water cycle "ends" ... oops - I mean, where it "begins."
