Urbanization causes: decreased forest area increased paved area increased soil erosion reduced flooding reduced population densit

Urbanization causes: decreased forest area ,increased paved area, increased soil erosion and reduced flooding.

Let's look into the choices one by one:

Decreased forest area- true.

As urbanization take place,much resources us needed to support the growing population and the technological development, woods from forest have been an inevitably abundant raw material.

Also, much flatland is needed for building infrastructures, in order to gain more flat land, forest is often cleared.

Trees are cut down for urban developement hence the forest area decrease.

Increased paved area - true

Much paved area is needed for urbanization for the traffic develoment as well as constructing roads to make places more acessible,resulting in increased paved area.

increased soil erosion - It depends.

If the government took efficient efforts to prevent land slide and carry out measures to prevent soil erosion, such as using shorcrete to prevent the increase of pore water pressure, the erosion can be reduced.

However if it is maintained poorly, the soil erosion is likely to increase as slopes are cut for flat land,aggravating the erosion.

Reduced flooding - It depends.

Again,whether the flooding will reduce or increase is up to government's maintenance and preventive measures for flooding.

Reduced population densit - false

As urbanization take place,the population percentage will only increase as it is one of the feature of urbanization.

Hope it helps!
