because Earth rotates because Earth tilts on its axis because gravity pulls Earth toward the Sun because the Moon reflects sunlight onto Earth
I gave my students this multiple choice question: On January 15th, there were 10 hours and 24 minutes of daylight in Jacksonville, Florida. On the same day, there were only 9 hours and 37 minutes of daylight in New York City. Why did New York have fewer hours of daylight than Florida?

Only one answer is correct among these 4 choices:
- because Earth rotates
- because Earth tilts on its axis
- because gravity pulls Earth toward the Sun
- because the Moon reflects sunlight onto Earth

Could you tell me which one is correct?

because Earth tilts on its axis
