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 diagram gives information about the cycle that

follows in

.

Overall

, the stages are nearly the same in both

areas

.

The first step is

the fall down of

water

during rainfalls and the

last

is the return of

water

to air by transpiration and evaporation. Between these steps, part of the

rocks. Urban

areas

are characterised by reduced infiltrations and so a decreased baseflow.

Furthermore

, the reduced infiltrations are converted into a higher polluted runoff.

This

leads to an increased erosion of the rock subsoil

that is

absent in the forested

areas

.

In addition

, the absence of trees in urban

areas

means that cities see a reduced amount of

water

that returns to air by transpiration and evaporation.
