Below are sample questions representative of the exercises included on this worksheet and related 9.142 Moon Phases, Eclipses, and Tides skill assessments:

Problem 1Difficulty: Mastery

A coastal planner notes that the largest tide range is expected two days after the exact full moon, not on the full moon date. Which interpretation is most scientifically reasonable?

ALocal ocean response can lag the astronomical alignment, even though the full moon helps drive spring tides.

BThe tide forecast proves the Moon phase has no relation to tides.

CThe Moon's gravity affects only weather and not ocean water.

DThe full moon must actually occur two days later everywhere on Earth.

Solution & Explanation:Astronomical alignment is a major driver, but real tide timing can be shifted by coastline shape, basin resonance, and local ocean response.

Problem 2Difficulty: Mastery

A lunar phase diagram is drawn without arrows for sunlight direction. Why is the model incomplete for identifying phases?

AThe Moon phase depends only on Earth's weather, so sunlight arrows are irrelevant.

BThe bright half of the Moon depends on which side faces the Sun, so the direction of sunlight is necessary.

CThe model needs ocean-current arrows but not sunlight arrows.

DThe model can identify every phase from Moon distance alone.

Solution & Explanation:Phase identification requires knowing which half of the Moon is illuminated by the Sun and how much of that half faces Earth.

Problem 3Difficulty: Mastery

Which data pattern would most strongly suggest neap tides rather than spring tides?

AHigh tides and low tides are close in height near a quarter Moon date.

BHigh tides are much higher and low tides much lower near new moon.

CThe tide range peaks twice in the month.

DThe Moon is full and a large range is measured.

Solution & Explanation:Neap tides have a small range and occur near first or third quarter, when the Sun and Moon act at right angles.
