2. Axis: imaginary line that passes through Earth’s center and the North & South Poles Earth’s axis tilt = 23.5° causes Earth’s seasons causes ‘length’ of day to change thruout the year

3. 23.5° Plane of orbit

4. Rotation : Earth’s spinning on its axis causes night & day Earth rotates every 24 hours

5. Revolution: movement of one object around another Earth revolves around the sun every 365.25 days

6. Orbit: an object’s path as it revolves around another object Earth’s orbit around the sun is slightly elliptical, not perfectly circular

7. 23.5° Plane of orbit

8. When we are tilted toward the sun, we have summer. When we are tilted away from the sun, we have winter

10. Equator: imaginary line encircling the Earth like a belt at 0° latitude All lines of latitude are measured as north or south of the equator.

11. Tropic of Cancer: latitude 23.5° N Tropic of Capricorn: latitude 23.5°S

12. Arctic Circle: latitude 66.5° N Antarctic Circle: latitude 66.5°S

13. Petal, MS: latitude ≈ 31.3° North (longitude ≈ 89.3° West)

15. Solstice: 2 days of the year when the noon sun is directly overhead at either 23.5° S or 23.5° N 1.Summer: longest “day” of year (daylight) Around June 21 st (northern hemisphere) 2.Winter: shortest “day” of year (daylight) Around Dec. 21 st (northern hemisphere)

16. Equinox: 2 days of the year when the noon sun is directly overhead at the equator (equal amt. of day & night) 1.Vernal (spring) Around March 21 st (northern hemisphere) 2.Autumnal (fall) Around Sept. 21 st (northern hemisphere)

20. Eclipse - when Earth or the moon temporarily block the sunlight from reaching the other. SUN, MOON and EARTH aligned perfectly 2 types of eclipse: 1. Solar eclipse 2. Lunar eclipse

21. Solar eclipse: moon moves between the Sun and Earth. view of sun is blocked by the moon can be total or partial occurs during the day moon phase = new moon

23. Lunar eclipse: Earth is between sun and moon Earth blocks sunlight from reaching the moon occurs at night moon phase = full moon
