3. The spinning of a Planet on its axis is called a rotation Earth rotates on its axis at about 1668 km/hour.  A person can rotate by standing in one place and turning around and around. Picture

4. Earth spinning on it’s axis gives us day and night

5. Only one half of the Earth faces the sun at any given time When Earth is facing the sun, it is daytime, when Earth is facing away from the sun, it is night time Picture

6. Earth completes one rotation on its axis in 24 hours, or one day

8. As Earth rotates on its axis, it also revolves or orbits around the sun

9. Go around something else Satellites, the space shuttle, space stations, and the Moon all orbit (go around) the Earth. The earth and all the other planets revolve around the sun. Caused by the gravitational pull of another object

10. Earth makes an orbit around the sun. Every 365.25 days (12 months or one year) earth makes a full revolution (or full orbit) around the sun. Picture

13. The earth is titled on its axis at 23.5° and it is always pointing in the same direction Pictures

14. The Earth experiences longer periods of day light when facing the sun

15. The Earth’s tilt and the orbiting of the Earth around the Sun causes the seasons.

16. When the North Pole is tilted toward the sun, the sun’s rays strike the Northern Hemisphere MORE directly, and this region is warmer When the South Pole is tilted toward the sun, the sun’s rays strike the Southern Hemisphere LESS directly, and this region is colder https://www.youtube.com/watch?v=9n04SEzuvXo

17. Near the equator sun rays hit Earth’s surface MORE directly, so temperatures are warmer there Near the poles, the sun rays hit the Earth’s surface LESS directly, so the temperatures are colder there

18. At Equator = 12 hours of day light Toward sun = more than 12 hours of day light Away from sun = less than 12 hours of day light Picture
