Question

Which of the following would happen in the absence of greenhouse effect in the atmosphere?

• A. Pollution will increase.
• B. The earth's surface temperature will decrease.
• C. The earth's surface temperature remains the same.
• D. The depleted ozone layer will increase the earth's temperature.

Answer 1

Answer: (B)

The earth's surface temperature will decrease.

When carbon dioxide and other air pollutants are collected in the atmosphere they absorb sunlight that has bounced from the earth’s surface. This leads to an increase in the earth's average surface temperature and is called global warming. When there is no effect of the global warming, the temperature of the Earth's surface will decrease.

Thus, the correct answer is option B.
