Review Solar System and things within

Students observe the planets on the computer screen. They note that the outer planets move more slowly and have larger orbits than the inner planets. Which question is best answered with this information?

• Why do the number of days in a year differ on different planets?

• Why do the outer and inner planets have different atmospheres?

• Why do the planets have different masses?

• Why do the planets orbit the sun instead of each other?

Which statement correctly explains observation 2 from student 3?

• The astronauts still experience the force of gravity but the space capsule and everything inside it are falling all at the same time.

• The astronauts still feel the force of gravity but they are so far away that gravity points away from earth.

• The astronauts are floating because they are too far away from Earth to have a mass.

• The astronauts are floating because their mass is too small to feel a force of gravity.

A student noticed that the model of the solar system was not correct. She noticed that there was really only one thing that was correctly represented. What was it that she found that was accurate?

• The size of the planets are an accurate size.
