Three questions on spinning, orbiting and the far side’s daylight.
No prior knowledge is needed. Choose an answer to see the explanation and evidence.
1Understanding
How many times does the Moon spin during one complete orbit around Earth?
Correct answer: It spins once.
One spin per orbit keeps almost the same face towards Earth. This is not a motionless Moon.
Evidence: The Moon spins once per orbit around Earth, so we see almost the same face. The key fact and diagram connect the two motions.
2Understanding
Which statement correctly separates rotation from orbiting?
Correct answer: Rotation is spinning about an object’s axis; orbiting is travelling around another body.
Rotation is an object’s own spin, while an orbit carries it around another body. The Moon does both.
Evidence: Rotation means spinning about an object’s own axis; orbiting means travelling around another body. The first section defines the two motions.
3Critical thinking
Which statement about the far side of the Moon is correct?
Correct answer: It receives sunlight and has changing days and nights.
The far side is defined relative to Earth. That is different from the direction of sunlight.
Evidence: It receives sunlight and has changing days and nights. The second section distinguishes our viewing direction from sunlight.
