Urbanization
Question 12
12.
What are some ecological advantages provided by established tropical forests?
(Select all that apply)
Increased biodiversity
Regulated local hydrological cycle
Stabilize soils
Carbon sink creation

Soil Erosion
Question 13
13.
Looking at the map, where is another location that clearcutting has occurred?
Question 14
14.
Clearcutting affects the water cycle by
Decreasing the amount of transpiration from trees due to chopping all of them down
Decreasing the amount of habitat due to chopping down the trees
Increasing the amount of evaporation from trees due to chopping all of them down
Increasing the amount of precipitation due to chopping down the trees
Question 15
15.
Clearcutting affects the carbon cycle by
Increasing the amount of CO
2
in the atmosphere by increasing photosynthesis
Decreasing the amount of CO
2
in the atmosphere by burning all of the trees
Increasing the amount of oxygen in the atmosphere by cutting down all the trees
Increasing the amount of CO
2
in the atmosphere from heating the soil and increasing decomposition due to loss of shade from trees
