question 18 (5 points)
listen
which process can affect the rate of carbon dioxide emissions or other greenhouse gas emissions by changing average temperatures?
a) axial precession
b) continental drift
c) cloud cover feedback
d) greenhouse gas feedback

Explanation:

For Question 17, thunderstorms require moisture to form clouds and precipitation, lifting to force air upward, and instability in the atmosphere to allow the air to rise freely. For Question 18, cloud - cover feedback can affect average temperatures. Clouds can either reflect sunlight (cooling effect) or trap heat (warming effect), thus influencing the rate of greenhouse gas emissions through temperature changes. Axial precession and continental drift have long - term geological and astronomical impacts not directly related to short - term greenhouse gas emission rates, and greenhouse gas feedback is more about the effect of emissions on temperature rather than the other way around in terms of the described process.

Answer:

Question 17: A. Moisture, lifting, and instability
Question 18: C. Cloud cover feedback
