What you’ll learn

  1. The ingredients of a cloudIdentify the water, particles, and moisture conditions needed for a cloud.Clouds are visible collections of tiny water droplets or ice crystals formed from atmospheric vapor.
  2. Cooling makes vapor condenseExplain how rising air cools to saturation and forms cloud droplets.Expansion lowers the temperature of rising moist air until vapor condenses on cloud condensation nuclei.
  3. Why clouds do not fallExplain how small particles and updrafts keep clouds suspended, and how rain begins.Tiny droplets fall slowly, while updrafts support them until growth makes precipitation heavy enough to fall.
  4. Clouds are constantly changingUse cloud shape and lifetime to connect condensation, motion, evaporation, and precipitation.A cloud is a changing process whose visible form records the atmosphere's current balance of moisture and motion.

Questions this course answers

What makes water vapor visible as a cloud?

Cooling air reaches saturation, allowing vapor to condense into droplets or ice crystals that scatter light.

What is a cloud condensation nucleus?

Dust, salt, pollen, smoke, and other aerosols provide surfaces where water molecules can gather.

Why can a small cloud droplet remain suspended?

A tiny droplet has a very low terminal fall speed, so turbulence and updrafts can keep it aloft.

When does a cloud particle become precipitation?

Growing droplets, raindrops, or ice crystals fall once their weight is greater than the support from air motion.

What is the best summary of why clouds persist?

A cloud lasts when rising, cooling, and condensation balance evaporation, mixing, and falling precipitation.
