Question

question 2 of 20 : select the best answer for the question. 2. 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 mark for review (will be highlighted on the review page) << previous question next question >>

Explanation:

• Option A: The ozone layer's width isn't directly related to greenhouse gases increasing the greenhouse effect. Greenhouse gases are different from ozone - related processes here.
• Option B: The stratosphere and mesosphere size changes are not mechanisms by which greenhouse gases enhance the greenhouse effect.
• Option C: Greenhouse gases (like CO₂, CH₄) trap infrared radiation (energy) emitted from the Earth's surface, keeping it in the atmosphere and thus increasing the greenhouse effect. This matches the scientific understanding.
• Option D: Greenhouse gases don't generate heat through mixing; they trap existing heat - energy in the atmosphere.

Answer:

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