Seasons of the Earth

 

23.   How does the Earth rotate, and how does that relate to day and night or the seasons?

24.   How does the Earth revolve, and how does that relate to day and night or the seasons?

25.   What causes the seasons? Is it the tilt of the Earth’s axis or its changing distance from the Sun throughout the year?
 
Gravity, Free Fall, and Orbits

 

26.   What is gravity, and how much weaker does it get as you get farther from the center of a body?

27.   Are objects in orbit of the Earth still under the influence of gravity?
