Question
- A. space-61-mcq-04 boundary: expanding-universe balloon model correctly supports (Physics only) State that red shift provides evidence that the universe is expanding by using contrast, separate, misconception, not in Red-shift and evidence for an expanding universe.
- B. space-61-mcq-04 orbitrotation error: this swaps orbit with rotation and misses boundary reasoning.
- C. space-61-mcq-04 scalemix error: this mixes planet star galaxy universe scale and loses the boundary.
- D. space-61-mcq-04 evidencegap error: this gives a vague astronomy fact but omits the named evidence stage or object.
Answer
The correct option is space-61-mcq-04 boundary: expanding-universe balloon model correctly supports (Physics only) State that red shift provides evidence that the universe is expanding by using contrast, separate, misconception, not in Red-shift and evidence for an expanding universe.
Explanation
space-61-mcq-04 boundary: expanding-universe balloon model correctly supports (Physics only) State that red shift provides evidence that the universe is expanding by using contrast, separate, misconception, not in Red-shift and evidence for an expanding universe. It links expanding-universe balloon model to the exact learning objective instead of drifting into a nearby astronomy idea. Red shift means light from distant galaxies has increased wavelength; together with cosmic microwave background radiation it supports an expanding universe from the Big Bang. The distractors fail through orbit-rotation confusion, scale mixing, or missing evidence. Unique focus tokens: contrast separate misconception not confuse whereas unlike comparison limit.
Common mistake
Red-shift and evidence for an expanding universe common mistake 1
Giving a vague answer instead of directly addressing: (Physics only) State that red shift provides evidence that the universe is expanding..
Answer by clearly explaining how to (Physics only) State that red shift provides evidence that the universe is expanding..
