Question 1: The greenhouse effect explains why a car's interior can get hot on a sunny day even if it is cool
outside. The glass windows allow the Sun's rays to pass through to the interior but
prevent heat rays from escaping to the outside. Certain gases, such as carbon dioxide and nitrous
oxide, act like the glass in a greenhouse when they are present in the atmosphere.
Both natural and human activities lead to the release of gases that contribute to the greenhouse
effect. During recent summers, forest fires have contributed to the loss of millions of acres of forest.
These fires have resulted in the release of smoke and ash as well as greenhouse gases.
Based on the information, which statement most likely predicts the result of ongoing widespread
forest fires?
A. Forest fires are unlikely to affect atmospheric temperature.
B. Forest fires decrease the amount of atmospheric greenhouse gases.
C. Greenhouse gases could help form new animal species.
D. There could be a gradual increase in average atmospheric temperatures.
E. There could be a gradual decrease in average atmospheric temperatures.
Correct Answer: D
