17 According to Newton’s law of universal gravitation every object in the universe (repels every other object) (attracts every other object) (moves randomly)

18 What happens to gravity as distance between objects increases (gravity increases) (gravity decreases) (gravity stays the same)

9 When the Northern Hemisphere is tilted toward the Sun it experiences (winter) (summer) (autumn)

12 What happens near the poles during summer (continuous darkness) (continuous daylight) (short days)

7 Why do we have seasons on Earth (Earth changes speed) (Earth’s axis is tilted and Earth revolves around the Sun) (the Moon moves closer)

3 What movement of Earth causes the four seasons (rotation) (revolution) (inertia)

14 What is an equinox (the Sun disappears) (day and night are equal) (gravity becomes weaker)

11 What happens near the poles during winter (continuous daylight) (continuous darkness) (equal day and night)

4 How long does Earth take to complete one rotation (24 hours) (365 days) (12 hours)

6 What is the pathway of a planet around the Sun called (axis) (orbit) (solstice)

1 What is the imaginary line that passes through Earth from the North Pole to the South Pole (orbit) (axis) (gravity)

15 During an equinox the Sun is directly over the (North Pole) (South Pole) (equator)
