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

Increase somewhat, some place more than others (primarily the polar regions)
Decrease somewhat, some place more than others (primarily the polar regions)
Decrease overall, some place more than others (primarily the tropical regions)
Increase overall, some place more than others (primarily the tropical regions)

Question 10
10.
What does the image represent?
Change in human population between 2000 and 2008
Change in forested area between 2000 and 2008
Change in biodiversity between 2000 and 2008
Question 11
11.
Describe
what 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.
Describe
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 13
13.
Explain
what generalization can be made about forest loss by year, dating from 2001 to 2014
Question 14
14.
What are some possible causes of these patterns?
Construction of roads and transportation access
Creation of nature preserves
Urbanization
Poaching
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
Decreasing the amount of habitat due to chopping down the trees
Increasing the amount of precipitation due to chopping down the trees
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
Question 18
18.
Clearcutting affects the carbon cycle by
Increasing the amount of CO
2
in the atmosphere from heating the soil and increasing decomposition due to loss of shade from 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
Decreasing the amount of CO
2
in the atmosphere by burning all of the trees
Maximizes profit
Question 2
2.
Question 3
3.
Why should we preserve forests?
They act as carbon storage sinks and prevent land degradation as well as habitats
They increase soil erosion
They increase habitat destruction
Which of the following are drawbacks and negatives of clearcutting?
(Select 4 correct answers)
Soil erosion
Releases CO
2
into the atmosphere
Flooding
Releases oxygen into the atmosphere

What are the benefits of maintaining healthy forests?
(Select 5 correct answers)
Forests prevent soil erosion
Forests create microclimates
Forests act as a carbon source when they release CO
2
Forests act as carbon storage (sequestration)
Forests act as habitats for many organisms

What are some ecological advantages provided by established tropical forests?
(Select 4 correct answers)
Soil Erosion

Regulated local hydrological cycle
Which of the following are impacts of deforestation?
(Select 4 correct answers)
