How does gravity affect the motion of the Earth and the Moon?

• It keeps the Earth stationary

• It causes the Earth to rotate

• It keeps the Moon in orbit around the Earth

• It causes the Moon to change shape

Explain how the Earth's tilt and orbit around the Sun cause the seasons to change.

• The tilt causes different parts of the Earth to receive varying amounts of sunlight throughout the year.

• The Earth's orbit changes speed, affecting the temperature.

• The tilt causes the Earth to move closer to the Sun in summer.

• The Earth's orbit is a perfect circle, causing consistent seasons.

DOK Level 3: Strategic Thinking

Predict what would happen if the Earth did not rotate on its axis.

• We would have longer days and nights

• The Moon would not orbit the Earth

• The seasons would change more frequently

• The Earth would stop moving around the Sun

Analyze why lunar eclipses do not occur every month.

• The Moon's orbit is tilted relative to the Earth's orbit around the Sun.

• The Sun is not always aligned with the Earth and Moon.

• The Earth's rotation speed changes monthly.

• The Moon's phases prevent it.

How does the gravitational pull of the Moon affect the Earth?

• It causes the Earth to rotate faster

• It creates ocean tides

• It changes the Earth's orbit

• It affects the Earth's temperature
