Understanding Earth Review
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:
Revolutionthe 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:
Axisan 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
Equator
Tropic of Cancer
Tropic of Capricorn
North Pole
South Pole
Arctic Circle
Antarctic Circle

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
Demonstrate Seasons:

What effects Climate:1. Latitude
1. Closer to equator = warmer2. Farther from equator = colder
2. Elevation1. Higher elevation = colder2. Lower elevation = warmer
3. Water1. Proximity (nearness in place)
1. Closer to water = more mild2. Farther away = more variation
2. Currents – warm and cold streams of water4. Wind – currents – warm and cold streams of air
Explain the Rain Shadow Effect:
Evaporation and cloud creation
Stage 1
Winds blow clouds upward
Backside is dry
Precipitation

Stage 1
Stage 3
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:
Northern Hemisphere
Inland
Away from
equator
This is near the equator. Near the equator, near water, Northern Hemisphere

Southern HemisphereSomewhat inlandNot real close to the equator, but not far away from it
Northern Hemisphere, far from equator, inland
Near equator and near water
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!
