Deforestation Questions: Test Your GK! Quiz
- 1.
Deforestation will most directly result in an immediate increase in:
- A.
Atmospheric carbon dioxide
- B.
Atmospheric ozone
- C.
Wildlife populations
- D.
Renewable resources
Correct Answer
A. AtmospHeric carbon dioxideExplanation
deforestation (cutting of trees) prevents trees from removing carbon dioxide from the atmosphere through photosynthesis. Increased carbon dioxide in the atmosphere contributes to global warming.Rate this question:

A greater stability of the biosphere would most likely result from:
- A.
Decreased finite resources
- B.
Increased deforestation
- C.
Increased biodiversity
- D.
Increased human populations
Correct Answer
C. Increased biodiversityExplanation
The biosphere (part of the earth where life exists) requires the cycles to run smoothly. Finite resources are non-renewable, including fossil fuels; deforestation is bad; human population increase means more deforestation and fossil fuel consumption. Increased biodiversity means more food webs...if one species dies, another can take its place...you need many organisms competing for specific niches in the ecosystem...in other words, MORE STABILITY.Rate this question:

One irreversible effect of both deforestation and water pollution on the environment is the:
- A.
Extinction of species
- B.
Thinning of the ozone shield
- C.
Depletion of atmospheric carbon dioxide levels
- D.
Increase in renewable resources
Correct Answer
A. Extinction of speciesExplanation
Irreversible means you can't go back. once an organism is extinct, it cannot come back. ALSO, cutting down trees removes the habitat and food sources for numerous species that rely on them for survival. BIODIVERSITY IS REDUCED.Rate this question:

Some people make compost piles consisting of weeds and other plant materials. When the compost has decomposed, it can be used as fertilizer. The production and use of compost is an example of:
- A.
The introduction of natural predators
- B.
The use of fossil fuels
- C.
The deforestation of an area
- D.
The recycling of nutrients
Correct Answer
D. The recycling of nutrientsExplanation
Just because you see the word deforestation doesn't make it a correct answer. Decomposed plant materials return nutrients to the soil for other plants to use...this is a cycle in nature. It's also disrupted by deforestation.Rate this question:

Deforestation of areas considered to be rich sources of genetic material could limit future agricultural and medical advances due to:
- A.
The improved quality of the atmosphere
- B.
The maintenance of dynamic equilibrium
- C.
An increase in the rate of evolutionary change
- D.
The loss of biodiversity
Correct Answer
D. The loss of biodiversityExplanation
Deforestation could cause species to go extinct (think Botana curus) that could eventually be used for food or medicine.Rate this question:

Most scientists recommend reducing carbon dioxide emissions. Less carbon dioxide in the atmosphere would be expected to:
- A.
Reduce the rate of global warming
- B.
Increase damage caused by acid rain
- C.
Decrease the number of biotic factors in ecosystems
- D.
Reduce destruction of the ozone layer
Correct Answer
A. Reduce the rate of global warmingExplanation
Increased carbon dioxide leads to global warming. Simple as that.Rate this question:

- 7.
Which human activity is correctly paired with its likely future consequence?
- A.
Overfishing in the Atlantic -- increase in supply of flounder and salmon as food for people.
- B.
Development of electric cars or hybrid vehicles -- increased rate of global warming
- C.
Use of fossil fuels -- depletion of underground coal, oil, and natural gas supplies
- D.
Genetically engineering animals -- less food available to feed the world's population
Correct Answer
C. Use of fossil fuels -- depletion of underground coal, oil, and natural gas suppliesExplanation
fossil fuels are nonrenewable...when we use them, we won't get them back. DEPLETION means removal or using up.Rate this question:
