You should spend about 20 minutes on this task. The diagram below shows the water cycle, which is the continuous movement of water on, above, and below the surface of the earth. Summarise the information by selecting and reporting the main features and make comparisons where relevant. Write at least 150 words.

The picture illustrates the natural process of the

water

cycle.

Overall

, the process involves three main stages: Ocean

water

evaporates, falls as rain, and eventually runs back into the oceans again. In the beginning stage, the ocean

water

evaporates because of the heat from the sun, and

this

causes

water

vapour to condense in the form of clouds. We can see that

of the vapours in the air. In the second phase, the

water

returns to the ground in the form of rain or snow, which is known as precipitation. At the final stage in the cycle, the rainwater may take several different routes. Some of the

water

may end up in lakes, or it may fall into rivers that eventually return to the oceans via surface runoff.

Otherwise

, rainwater may seep through the ground and reach the earth’s impervious layer.

Also

, saltwater intrusion is demonstrated to occur shortly before groundwater enters the oceans to complete the cycle.
