What is the primary role of condensation nuclei in the formation of clouds?
What is the primary role of condensation nuclei in the formation of clouds?
- Condensation nuclei cause the water vapor in the atmosphere to evaporate
- Condensation nuclei have no impact on cloud formation
- Condensation nuclei act as centers for water vapor to accumulate and form water droplets (correct)
- Condensation nuclei prevent the formation of clouds by inhibiting water vapor condensation
