Water Cycle Water is a substance that moves in a

cycle. It has no beginning or end. It moves throughout the whole

biosphere

Water cycle Sun’s heat warms the

surface water and the water evaporates into the atmosphere

In the atmosphere the water exists as a gas (water vapour)

When water vapour cools it condenses to form clouds

Water Cycle From clouds, it may fall to the Earth as

rain, hail, snow or sleet.

Run-off Liquid that is not absorbed by the run

off the surface into nearby streams or rivers.

aquifers Some water seeps down through the soil

into the ground water. Some ground water may flow into larger underground lakes

Water Cycle Some of the water on

the surface or in the soil is taken up by animals and plants

Plants have a major role in the water cycle. Transpiration- plants

release water vapour into the atmosphere through their leaves.
