Which process describes water vapor turning into liquid water in the atmosphere?

• A. Evaporation
• B. Condensation
• C. Sublimation
• D. Precipitation

Answer: (B)

Condensation is the change of water from a gas to a liquid when water vapor in the air cools and reaches its dew point. As air cools, vapor molecules slow down and cling together, forming tiny liquid droplets that create clouds, fog, or dew on surfaces. This is the process you observe when mist turns into visible cloudiness in the sky or on a cool morning. Evaporation would be liquid water turning into water vapor, not the other way around. Sublimation is solid turning directly into gas, skipping the liquid phase. Precipitation refers to condensed water falling to Earth's surface as rain, snow, or hail.
