Module 7 Week 2 HMH

Which statement describes a limitation of the model?

• It cannot show how the planets orbit the sun.

• It cannot show the relative sizes of each planet.

• It does not show the gravitational force exerted by each planet.

• It does not show the order of the planets, from closest to the sun to farthest from the sun.

Is this model to scale regarding the sizes of the planets and distances between them? Why or why not?

• Yes. That's why the outer planets are showin in a separate table

• No. The distances in the solar system are too great to produce a model accurate to distance that still has inner planets visible.

• No. The outer planet distances are drawn to scale, but the inner planets need to be drawn farther from the sun to be visible.

Answer explanation

The sizes of the planets and their distances from the sun make it nearly impossible to show both scale in a model that fits on a single page.

How can the observed phases of Venus provide evidence to support a specific model of the Solar System? Check three (3) that apply.

• The model that better predicts the phases is likely to be more correct.

• The phases of Venus follow a predictable pattern that results from the relative positions of the Sun, Venus, and Earth.

• Neither model accurately predicts the observed phases of Venus, so neither model is accurate.

• The models predict the phases of Venus differently beause the relative positionsof the three bodies are different in each model.

Answer explanation

A, B, D; The difference between the models is the relative positions of the sun, Earth, and Venus.

Based on the model, why are Ceres and Pluto classified as dwarf planets rather than planets?

• Ceres and Pluto are both round

• Dwarf planets have irregularly shaped orbits and planets have elliptical orbits

• Neither Ceres nor Pluto has cleared its orbital path of other objects

Answer explanation

The plents in the model have cleared their orbit paths, but Ceres and Pluto have not so they cannot be true planets. Ceres is in the asterioid belt, Pluto is in the Kuiper Belt, but true planets do not exist in orbital paths containing other large space ojects. Both planets and dwarf planets are round, and both types of ojects have elliptical orbits.
