Deforestation Questions: Test your GK! Quiz

1. Which human activity is correctly paired with its likely future consequence?

Overfishing in the Atlantic -- increase in supply of flounder and salmon as food for people.

Development of electric cars or hybrid vehicles -- increased rate of global warming

Use of fossil fuels -- depletion of underground coal, oil, and natural gas supplies

Genetically engineering animals -- less food available to feed the world's population

fossil fuels are nonrenewable...when we use them, we won't get them back. DEPLETION means removal or using up.

Explanation

fossil fuels are nonrenewable...when we use them, we won't get them back. DEPLETION means removal or using up.

2. 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:

The introduction of natural predators

The use of fossil fuels

The deforestation of an area

The recycling of nutrients

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.

3. Deforestation will most directly result in an immediate increase in:

Atmospheric carbon dioxide

Atmospheric ozone

Wildlife populations

Renewable resources

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.

Explanation

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.

4. Deforestation of areas considered to be rich sources of genetic material could limit future agricultural and medical advances due to:

The improved quality of the atmosphere

The maintenance of dynamic equilibrium

An increase in the rate of evolutionary change

The loss of biodiversity

Deforestation could cause species to go extinct (think Botana curus) that could eventually be used for food or medicine.

Explanation

Deforestation could cause species to go extinct (think Botana curus) that could eventually be used for food or medicine.

5. Most scientists recommend reducing carbon dioxide emissions. Less carbon dioxide in the atmosphere would be expected to:

Reduce the rate of global warming

Increase damage caused by acid rain

Decrease the number of biotic factors in ecosystems

Reduce destruction of the ozone layer

Increased carbon dioxide leads to global warming. Simple as that.

Explanation

Increased carbon dioxide leads to global warming. Simple as that.

6. A greater stability of the biosphere would most likely result from:

Decreased finite resources

Increased deforestation

Increased biodiversity

Increased human populations

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.

7. One irreversible effect of both deforestation and water pollution on the environment is the:

Extinction of species

Thinning of the ozone shield

Depletion of atmospheric carbon dioxide levels

Increase in renewable resources

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.
