The correct answers are:
- decreased forest land;
In order for the urbanization to take place, the natural areas, usually forests and grasslands, need to be cleared. With the clearing out of them, the forests and grasslands are decreasing as they have been ruined and occupied with infrastructure.
- increased paved surfaces;
The urbanization predicts the building of lot of infrastructure, big portion of which is with concrete and asphalt, thus significantly increasing the paved surfaces.
- increased soil erosion;
Because of the aforementioned clearing of the forests and grasslands, the soil loses its natural protection from erosion, so the soil that is left like that on the open will be very vulnerable to the erosion.
