Write IELTS essay task 1 with at least 150 words with the topic "The diagram below shows the water cycle, which is the continuous movement of water on, above and below the surface of the Earth. Summarize the information by selecting and reporting the main features and make comparisons where relevant."

The picture illustrates the natural process known as the

water

cycle in which

water

passes from the

ocean

to the air and

then

to land. As shown on the diagram, there are three main stages including evaporation, precipitation and running back into the

ocean

. The process begins with evaporation. In

this

stage, 80% of

water

vapour in the air comes from the

ocean

. Heat from the sun causes

water

to evaporate, and

water

vapour condenses to form clouds. When it comes to the second stage, called precipitation,

water

falls as rain or snow. At the third stage in the cycle, rainwater may take various paths. Some of it may fall into lakes or return to the

ocean

via ‘surface runoff’. In another way, rainwater may run under the ground, reaching the impervious layer of the earth. Groundwater can be intruded by salt

water

before it passes into the

ocean

to complete the cycle.
