Sample General Science questions
1. Some scientists have suggested that the Moon was formed when a large body struck Earth and broke off a piece of Earth billions of years ago. Which observation would best support this suggestion?
- (A) The Earth and the Moon are gravitationally locked together.
- (B) The chemical composition of Moon rocks is similar to Earth rocks.
- (C) The rocks of the Moon are older than Earth rocks.
- (D) The Earth has free standing water, but the Moon does not.
Show answer
(B) The chemical composition of Moon rocks is similar to Earth rocks.. Concept: The Giant Impact Hypothesis says a Mars-sized body (Theia) hit the early Earth and the debris formed the Moon. If the Moon is made of Earth material, its rocks should chemically resemble Earth's. Why B is correct: Apollo samples show Moon rocks have almost the same oxygen-isotope ratios and silicate composition as Earth's mantle — direct evidence that the Moon's material came from Earth. Why others are wrong: - A) Tidal locking happens to many moons regardless of origin. - C) Moon rocks are not older than Earth; both are about 4.5 billion years old. - D) Absence of water on the Moon does not tell us where its material came from. Remember: Moon origin theories: fission, capture, co-formation, giant impact (accepted). Evidence for impact: similar composition, low iron content of Moon, Earth's tilt.
2. According to the periodic table, argon is found in what column?
- (A) 2 (2A)
- (B) 1 (1A)
- (C) 16 (6A)
- (D) 18 (8A)
Show answer
(D) 18 (8A). Correct answer: 18 (8A).
3. Which structure surrounds and protects an animal cell?
- (A) Nucleus
- (B) Cytoplasm
- (C) Vacuole
- (D) Cell membrane
Show answer
(D) Cell membrane. Correct answer: Cell membrane.
