  • Increase in temperature
  • Decrease in water vapor content
  • Decrease in cooling rate
  • How does air temperature affect the capacity of holding water vapor?

  • It decreases as air temperature increases
  • It increases as air temperature increases (correct)
  • It depends on the time of day
  • It remains constant regardless of the temperature
  • What are condensation nuclei?

  • Tiny particles like dust or pollen in the atmosphere (correct)
  • Gaseous particles that help with cloud formation
  • Microscopic water droplets in the air
  • Particles that absorb cloud droplets
  • In the context of cloud dissipation, what does it mean when the cloud droplets evaporate?
