Below are sample questions representative of the exercises included on this worksheet and related 8.104 Seasons and Axial Tilt skill assessments:

Problem 1Difficulty: Mastery

Which explanation best connects axial tilt, daylight, and solar intensity in one causal chain?

ABecause the Moon pulls on Earth, the Sun rises higher only during full moons.

BBecause Earth rotates, every location has the same season and the same daylight all year.

CBecause Earth's orbit is slightly elliptical, each hemisphere becomes summer at the same time.

DBecause Earth's axis is tilted and stays nearly parallel during revolution, each hemisphere alternately receives longer, more direct sunlight and shorter, less direct sunlight.

Solution & Explanation:The complete causal chain starts with tilt and revolution, then explains changes in daylight duration and light angle that create seasonal patterns.

Problem 2Difficulty: Mastery

The planned chart compares solar angle at noon for the same city: 28 degrees in December, 51 degrees in March, 74 degrees in June, and 50 degrees in September. Which interpretation is best?

AThe city is closest to the Sun in December because the angle is smallest.

BThe city receives exactly the same solar intensity all year.

CThe city receives its most direct noon sunlight near June.

DThe city has no seasons because March and September are similar.

Solution & Explanation:The highest noon solar angle means the most direct sunlight, which increases solar intensity near the summer solstice.

Problem 3Difficulty: Mastery

A researcher compares two possible causes of seasons. Model A changes Earth-Sun distance but keeps Earth untilted. Model B keeps distance constant but tilts Earth 23.5 degrees as it revolves. Which model better explains opposite hemisphere seasons?

AModel A, because distance changes always affect only one hemisphere.

BModel B, because tilt makes one hemisphere receive more direct light while the other receives less.

CBoth models equally explain opposite seasons without any data.

DNeither model can include daylight length.

Solution & Explanation:Opposite hemisphere seasons require different sunlight angles and daylight lengths in the two hemispheres at the same time, which the tilt model provides.
