Below are sample questions representative of the exercises included on this worksheet and related 9.125 Humidity, Clouds, and Precipitation skill assessments:

Problem 1Difficulty: Mastery

Which sequence best summarizes how an ocean water molecule can become part of rain over land?

ARunoff into clouds, melting into vapor, and falling upward as rain.

BEvaporation from the ocean, transport by wind, uplift and cooling, condensation into cloud droplets, growth, and precipitation.

CCondensation in the ocean, sinking through rock, warming into wind, and avoiding the atmosphere.

DPrecipitation from land, freezing in soil, direct movement into sunlight, then evaporation into a cloudless sky.

Solution & Explanation:The correct sequence follows water and energy through the atmosphere: evaporation adds vapor, wind transports it, uplift cools it, condensation forms cloud particles, and growth allows precipitation.

Problem 2Difficulty: Mastery

A humidity chart over one day shows 95% RH at 5 a.m., 70% at 9 a.m., 45% at 2 p.m., and 60% at 8 p.m. If surfaces cooled overnight, when was dew most likely?

A5 a.m.

B2 p.m.

C9 a.m.

D8 p.m.

Solution & Explanation:Dew is most likely when relative humidity is highest and surfaces are coolest, often near sunrise. At 95% RH, only a little additional cooling is needed for saturation.

Problem 3Difficulty: Mastery

A valley receives rain while a nearby mountain pass receives snow during the same storm. Which explanation is most likely?

ARain cannot occur in valleys unless mountains produce hail first.

BThe mountain pass is colder because of elevation, so falling snow is less likely to melt before reaching the surface.

CThe precipitation type depends only on wind direction and not on temperature profile.

DSnow at higher elevations proves the valley air contains no water vapor.

Solution & Explanation:Temperature generally decreases with altitude in the troposphere. A colder mountain pass may keep precipitation frozen while lower, warmer valley air melts snow into rain.
