1. Understanding Earth Review

2. Rotation (rotates) – spinning on the axis (turns)
What does rotation give Earth and how long does it take to rotate?
The concept of night and day – it takes 24 hours to rotate one time
What does rotation look like, demonstrate it:

3. Revolution the journey around the sun Demonstrate revolution:
How long does it take and what concept of time does it give Earth?
365¼ days – it gives us the concept of a year

4. Axis
an imaginary line that passes through the center of Earth from the North Pole to the South Pole that Earth turns around…it tilts at 23½° angle

5. 66N North Pole 23½N Arctic Circle 0 Tropic of Cancer 23½S Equator

6. Why do we have seasons?
With the tilt of the earth and the revolution around the sun, the Earth experiences different seasons:
When is it summer?
When the hemisphere is tilted towards the sun
When is it winter?
When the hemisphere is tilted away from the sun
Seasons are…
Opposite
What are the solstices?
Summer = longest day of the year (daylight)
Winter = shortest day of the year (darkness)
Equinoxes are…
When the earth is directly above the equator and is not tilted towards or away from the sun
Spring and Fall

Indian Ocean 10
Australia 11 3
Antarctica 12

9. What effects Climate: Latitude Elevation Water
Closer to equator = warmer
Farther from equator = colder
Elevation
Higher elevation = colder
Lower elevation = warmer
Water
Proximity (nearness in place)
Closer to water = more mild
Farther away = more variation
Currents – warm and cold streams of water
Wind – currents – warm and cold streams of air

10. Winds blow clouds upward
Explain the Rain Shadow Effect:
Stage 3
Precipitation
Stage 4
Stage 2
Winds blow clouds upward
Stage 1
Backside is dry
Evaporation and cloud creation
Stage 1

11. What does these graphs tell you…analyze them and tell why they are the way they are…
Use your 4 factors of climate and think about which hemisphere they are in:

12. Northern Hemisphere
Inland
Away from
equator

13. This is near the equator.
Near the equator, near water, Northern Hemisphere

14. Not real close to the equator, but not far away from it
Average high °F 82 81 76 68 60 54 53 55 61 67 73 79
Southern Hemisphere
Somewhat inland
Not real close to the equator, but not far away from it

15. Northern Hemisphere, far from equator, inland

16. Near equator and near water

17. You are going to do great on this
You are going to do great on this! Let me know if you have any questions or need anything at all.
You will demonstrate the rotation, revolution, axis, solstices, and equinoxes with your body or with a globe.
Have a super duper night!
