Question 4
4.
Why do loggers clearcut forests?
They are making sure that there is enough land for agriculture
It is the fasest and most economically viable method
They are trying to save as much of the habitat for organisms as they can
It is the most environmentally friendly method

Question 10
10.
What does the image represent?
Change in human population between 2000 and 2008
Change in biodiversity between 2000 and 2008
Change in forested area between 2000 and 2008
Question 11
11.
What do the colors represent?
Click the "details" box on the left side and click the "content" box. Check the "Forest Loss (World Land Cover)" box.
Question 12
12.
What is the relationship between the original green image and the red image?
Click the checkbox to the left of the layer name, Forest Loss (by year). Compare the current map with the years 2000, 2004, and 2008.

Question 14
14.
What are some possible causes of these patterns?
Creation of nature preserves
Poaching
Construction of roads and transportation access
Urbanization
Question 15
15.
Question 16
16.
Looking at the map, where is another location that clearcutting has occurred?
Question 17
17.
Clearcutting affects the water cycle by
Increasing the amount of evaporation from trees due to chopping all of them down
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 precipitation due to chopping down the trees
Question 18
18.
Clearcutting affects the carbon cycle by
Decreasing the amount of CO
2
in the atmosphere by burning all of the trees
Increasing the amount of CO
2
in the atmosphere by increasing photosynthesis
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
Increases soil erosion
Question 2
2.
Which of the following are impacts of deforestation?
Increased soil and stream temperature
Increased sedimentation and nutrient runoff
Habitat destruction
Increased flooding
Question 3
3.
Why should we preserve forests?
They increase soil erosion
They act as carbon storage sinks and prevent land degradation as well as habitats
They increase habitat destruction
Which of the following are drawbacks and negatives of clearcutting?
(Select all that apply)
Increased soil and stream temperatures
Releases CO
2
into the atmosphere
Releases oxygen into the atmosphere
Flooding
Decreased soil and stream temperatures
Soil erosion
Forests prevent soil erosion
Forests act as habitats for many organisms
Forests act as carbon storage (sequestration)
Forests absorb pollutants from the atmosphere
What are some ecological advantages provided by established tropical forests?
(Select all that apply)
Regulated local hydrological cycle
Stabilize soils
Decreased biodiversity
Carbon sink creation
Increased biodiversity
Soil Erosion
