Why are sometimes closer to the sun at certain points in their orbit?
The sun's strength changes over time and its gravity pulls harder in some months
The planets have an elliptical (slight oval) orbit that brings them a little closer to the sun
The sun moves back and forth throughout the year
Planets orbit in a perfect circle and the sun is always equi-distant from the planets
What description best defines a dependent (outcome) variable in a scientific experiment?
ANY factor that is observed and measured to gather data
ANY factor that is controlled during an experiment
ANY factor that stays the same during the experiment
ANY factor that is changed by the scientist so that its effect can be tested
The orbit or motion of the planets around the sun is a result of inertia and ________?

Elliptical force
Gravity
Magnetism
Mercury is closer to the sun than Venus. Why is Venus hotter than Mercury?
Venus has a thicker atmosphere to absorb and keep the heat
Mercury is too small and cannot absorb or retain heat
Venus does not have an atmosphere so it's surface absorbs all of the heat
Mercury has a thicker atmosphere so it absorbs and retains more heat

The planets formed; a nebular cloud formed; then the sun formed
The sun formed; the planets formed; then a nebular cloud formed
The planets formed; then the sun formed; and then a nebular cloud formed
Because Jupiter is farther from the sun than Earth, what can you conclude about Jupiter's length and duration (time) of it's orbit?
Jupiter has a larger orbit so it takes less time to go around the sun
Jupiter has a smaller orbit so it takes more time to go around the sun
Jupiter has a smaller orbit so it takes less time to go around the sun
Jupiter has a larger orbit so it takes longer to go around the sun
The sun generates energy by nuclear fusion. Which statement best describes what hapens during the process of nuclear fusion in the sun?
Dark spots form on the surface of the sun
