Chapter 17: Problem 32

Greenhouse effect keeps the earth surface (A) Cold at night (B) Dusty and cold (C) Warm at night (D) Moist

Short Answer

Expert verified
The greenhouse effect helps to maintain a warmer temperature on the earth's surface, especially at night when there is no direct heat from the sun. So, the correct statement is (C) Warm at night.

Step by step solution

01

Option A: Cold at night

The greenhouse effect actually traps heat within the atmosphere, so it does not make the earth cold at night. Therefore, option A is incorrect.
02

Option B: Dusty and cold

The greenhouse effect is not responsible for making the earth dusty or cold. Its primary impact is related to trapping heat and maintaining temperatures. So, option B is incorrect.
03

Option C: Warm at night

The greenhouse effect traps heat within the atmosphere, which in turn helps to maintain a warmer temperature on the earth's surface, especially at night when there is no direct heat from the sun. Therefore, option C is the correct answer.
04

Option D: Moist

The greenhouse effect does not directly contribute to the moisture content in the atmosphere. It is primarily concerned with heat and temperature regulation. Hence, option D is incorrect.
05

Conclusion

The correct statement about the greenhouse effect on the earth's surface is: (C) Warm at night
