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

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 Equator Tropic of Cancer Tropic of Capricorn North Pole South Pole Arctic Circle Antarctic Circle 66  N 66  S 23½  N 23½  S 00 Axis

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

7 Demonstrate Seasons:

8 Pacific Ocean Atlantic Ocean Indian Ocean Arctic Ocean North America Europe Asia Africa South America Australia Antarctica

9 What effects Climate: 1.Latitude 1.Closer to equator = warmer 2.Farther from equator = colder 2.Elevation 1.Higher elevation = colder 2.Lower elevation = warmer 3.Water 1.Proximity (nearness in place) 1.Closer to water = more mild 2.Farther away = more variation 2.Currents – warm and cold streams of water 4.Wind – currents – warm and cold streams of air

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

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 Average high °F 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! 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!
