  2. What do we use to represent different objects or systems on Earth?

  3. Models • Models –

  4. Some examples include:

  5. Evidence for Earth’s Shape

  6. 1)____

  7. 2) Lunar Eclipse –

  8. 3)___

  9. Actual shape of the Earth Flatter at poles, wider at equator , caused by…. _________________

  10. Earth’s Shape–_________ But Earth appears to be a perfect sphere from space!

  11. Bulge inward - Greater gravitational pull Closer to the center of gravity Center of gravity Bulge outward Less gravitational pull further away from center of gravity

  12. How could we figure out what the circumference of the Earth is?

  13. I think the Earth is round. I have an Idea!!! Also, the Sun’s rays are parallel.

  14. Than we could use the following formula to determine the circumference of the Earth If I know the distance between two points on the Earth 7 Degrees 4900 Stadia 0 Degrees and if the angle of the shadow created by the Sun’s rays at one of the locations is 0 degrees and I know the angle of the shadow created at the second location
