The diagram below shows the water cycle in both forested and urban areas. Summarise the information by selecting and reporting the main features and make comparisons where relevant.

The two diagrams illustrate the differences between the

water

cycle in forests and cities. Looking from an

overall

perspective, it is readily apparent that both cyclical natural illustrations have 6 main stages, beginning with evaporation and transpiration and culminating in runoff. First of all,

water

starts to evaporate in forested areas ,and at the same time, the transpiration phase occurs.

Subsequently

, after the condensation process, evaporated

water

turns into precipitation and rains from the clouds. In the next stage, during the infiltration phase,

water

undergoes permeable and less permeable soil layers, and

then

, flows through baseflow which results in runoff. In terms of soil erosion in urban areas,

firstly

, reduced evaporation and transpiration levels happen.

Consequently

, the purification of

water

declines in cities which may bring about the baseflow reduction.

Finally

, decreased amounts in the aforementioned stages lead to an increase in land degradation which can cause high numbers of pollutants within soil.
