- Use the diagram (images may not be to scale). Which statement about these objects is supported by the visual evidence?
- Object 1: large sphere with swirling bands and a thick outer layer drawn around it (atmosphere)
- Object 2: smaller sphere with many craters and no outer layer drawn
- Object 3: irregular rocky chunk with craters
- Object 4: bright head with a tail
Answer: Objects 2 and 3 are more similar to each other than to Object 4 because both have rocky, cratered surfaces and no tail.
The core skill in earth and space science involves comparing space objects using visual evidence from images or models. Space objects vary widely in features like their shape, surface characteristics, and surrounding elements such as atmospheres or tails. Similarities and differences can be identified by closely examining these features in provided images or simplified models. A useful checking strategy is to list observable features for each object and then compare them across the different objects. One common misconception is that size or a single appearance trait alone determines the type of space object, but multiple features must be considered together. By carefully comparing this evidence, scientists can classify space objects more accurately. This process helps in understanding their origins, compositions, and behaviors in the solar system.
- A student claims: "If an object is round, it is always a planet." Use the diagram (images may not be to scale). Which claim about object type is incorrect based on the visual evidence?
Objects shown:
- Object A: spherical, cratered (no atmosphere layer drawn)
- Object B: spherical with atmosphere layer drawn
- Object C: irregular rocky chunk
- Object D: bright head with tail
Answer: Object A must be a planet because it is round.

- Use the diagram (images may not be to scale). Which two objects are most similar based on observable features?
- Object A: irregular, rocky, cratered
- Object B: irregular, rocky, cratered
- Object C: spherical with a visible atmosphere layer drawn
- Object D: bright head with a long tail
Answer: Objects A and B

- Study the diagram of four space objects (images are simplified models and may not be to scale). Which object is different from the others based on the evidence that it has a visible tail?
Objects shown:
- Object A: irregular, rocky, heavily cratered surface; no tail
- Object B: bright head with a long, fuzzy tail pointing away; smooth-looking head
- Object C: nearly spherical, cratered surface; no tail
- Object D: small, irregular rocky chunk; no tail
Answer: Object B

- Use the diagram (images may not be to scale). Which claim about object type is incorrect based on the visual evidence?
- Object X: bright head with a long tail
- Object Y: irregular rocky chunk with craters
- Object Z: spherical, cratered body with no atmosphere layer drawn
- Object W: spherical body with a visible atmosphere layer drawn
Answer: Object Z must be a comet because it is round.
