Below are sample questions representative of the exercises included on this worksheet and related 9.144 Solar System Objects and Formation skill assessments:

Problem 1Difficulty: Mastery

Use the concept map to answer the question. Which branch should include asteroids, comets, and meteoroids?

ALayers of Earth's atmosphere

BMajor planets only

CSmall solar system bodies

DArtificial spacecraft

Solution & Explanation:Asteroids, comets, and meteoroids are small solar system bodies. They are not major planets, spacecraft, or atmospheric layers.

Problem 2Difficulty: Mastery

A comet spends most of its orbit far from the Sun but becomes bright during a short inner-solar-system passage. Which explanation is best?

AIt becomes bright because it stops moving and fuses hydrogen like the Sun.

BIts elongated orbit brings icy material close enough for solar heating to release gas and dust briefly.

CIt is a meteorite resting on the ground during most of its orbit.

DIt turns into a terrestrial planet whenever it passes Jupiter.

Solution & Explanation:Many comets have elongated orbits. They become active and bright mainly near the Sun, where heating causes ices to sublimate and release gas and dust.

Problem 3Difficulty: Mastery

Some meteorites contain presolar grains, tiny mineral grains older than the solar system. What is the best interpretation of this evidence?

APresolar grains prove all planets are younger than humans.

BMeteorites are created only by modern lightning on Earth.

CThe solar nebula included material made before the Sun formed.

DThe solar system formed without any earlier stellar material.

Solution & Explanation:Presolar grains show that some solid material in meteorites formed before the Sun, meaning the solar nebula contained material inherited from earlier stars.
