Below are sample questions representative of the exercises included on this worksheet and related 9.64 Radiation skill assessments:

Problem 1Difficulty: Mastery

Use the steady-state energy diagram: 100 units of sunlight enter the Earth system. The diagram shows 25 units reflected by clouds, 5 units reflected by the surface, and 70 units absorbed. Which outgoing energy flow must be included for conservation at steady state?

A25 units absorbed again by the clouds forever

B70 units conducted through empty space to the Sun

C100 additional units created by Earth's surface

D70 units emitted to space mostly as infrared radiation

Solution & Explanation:At steady state, total outgoing energy must balance incoming energy. If 30 units are reflected and 70 absorbed, the absorbed 70 units must eventually leave, mostly as infrared radiation.

Problem 2Difficulty: Mastery

Frost is more likely on a clear, calm night than on a cloudy night with the same afternoon temperature. Which radiation process helps explain this?

ACalm air turns infrared radiation into conduction from the Sun.

BThe ground can lose more infrared radiation to space under a clear sky.

CThe ground receives more visible sunlight at midnight under a clear sky.

DClouds stop all heat transfer between the ground and air.

Solution & Explanation:Under clear skies, infrared radiation from the ground can escape more easily to space, causing stronger surface cooling that can promote frost.

Problem 3Difficulty: Mastery

A passive-solar classroom has sun-facing windows and a dark tile floor. Which radiation explanation best describes the design?

AThe floor warms only because cold air sinks into the tiles.

BThe windows conduct heat directly from the Sun through space.

CThe dark floor reflects all sunlight back out the windows.

DSunlight enters and is absorbed by the dark floor, increasing the floor's thermal energy.

Solution & Explanation:The design uses incoming solar radiation. The dark tile absorbs light energy and converts it into thermal energy.
