Use the scenario to answer the question.

A student is making a model that compares comets and planets.

Which comparison could be part of the model?

(1 point)

O Comets and planets have similar orbital time periods.

Comets and planets revolve around the sun.

Comets and planets are comprised of the same materials.

Comets and planets have similar sizes.

All of the comparisons could be part of the model, but the most accurate comparison would be that comets and planets revolve around the sun.

The comparison that could be part of the model is that "Comets and planets revolve around the sun."

To answer this question, we need to analyze the scenario and find the information that could be included in the model comparing comets and planets.

The scenario states that the student is making a model that compares comets and planets. This implies that the model should highlight some similarities or differences between the two.

Option 1, "Comets and planets have similar orbital time periods," is not a valid comparison because comets and planets have different orbital time periods. Comets have highly elliptical and elongated orbits, whereas planets have more circular orbits.

Option 2, "Comets and planets revolve around the sun," is a valid comparison that can be included in the model. Both comets and planets orbit around the sun, though they have different types of orbits.

Option 3, "Comets and planets are comprised of the same materials," is not a valid comparison. While planets are predominantly made up of rocky or gaseous materials, comets are composed primarily of ice, dust, and small rocky particles.

Option 4, "Comets and planets have similar sizes," is not a valid comparison. Planets are generally much larger than comets. Comets are typically smaller and more irregularly shaped.

Therefore, the valid comparison that could be part of the model comparing comets and planets is: "Comets and planets revolve around the sun."
