Question

question 17 (5 points) listen how do gases increase the overall greenhouse effect? a) increasing the overall width of the ozone b) increasing the size of the stratosphere and decreasing the size of the mesosphere c) trapping energy from the sun in the earths atmosphere d) generating heat through mixing of the gases

Explanation:

To solve this, we analyze each option:

• Option A: Ozone width isn't related to greenhouse gases' effect on the greenhouse effect. Greenhouse gases (like CO₂, CH₄) are different from ozone, so A is incorrect.
• Option B: The stratosphere and mesosphere size changes aren't how greenhouse gases increase the greenhouse effect. The greenhouse effect is about heat trapping, not atmospheric layer size, so B is wrong.
• Option C: Greenhouse gases (e.g., carbon dioxide, methane) trap infrared radiation (energy) emitted by the Earth, keeping it in the atmosphere and warming it. This matches the mechanism of the greenhouse effect, so C is correct.
• Option D: Greenhouse gases don't generate heat by mixing; they trap existing heat (infrared energy) from the Earth, so D is incorrect.

Answer:

C) Trapping energy from the sun in the earth's atmosphere
