In a hypothetical planetary system, planet A is 20 million kilometers from the star, and planet B is 60 million kilometers from the star. Which statement is true concerning the orbit of these planets? Choose the correct answer.
Planet A moves faster than planet B because it is closer to the star.
Planet B moves faster than planet A because it is farther from the star.
Planet A has an orbit more elliptical than planet B’s orbit because it is closer to the star.
Planet B has an orbit more elliptical than planet A’s orbit because it is farther from the star.

- 3. Multiple Choice
What evidence demonstrates the interaction between Earth’s magnetic field and solar wind? Choose the correct answer.
spring tides
solar eclipses
the aurora borealis
the greenhouse effect
- 4. Multiple Choice
Why does the moon have more impact craters on its surface than Earth does? Choose the correct answer.
Earth’s gravity causes more objects to collide with the moon than with Earth.
Most of Earth’s impact craters have been destroyed by plate tectonics and erosion.
Earth’s magnetic field deflects more objects than the very weak magnetic field of the moon does.
The rocks that compose the moon’s surface are more easily deformed than Earth’s surface rocks.
