Looking at the map, where is another location that clearcutting has occurred?

1

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

1

Clearcutting affects the carbon cycle by

Increasing the amount of CO₂ in the atmosphere by increasing photosynthesis

Decreasing the amount of CO₂ 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 CO₂ in the atmosphere from heating the soil and increasing decomposition due to loss of shade from trees
