The Planet Earth

What is the Shape of the Earth?

Tagbanwas of Palawan Believed that land is mostly mountains surrounded by water, and underneath is an exact but inverted image of land and water and all that are in them.

Shape of the Earth About 100 BC to 1500 AD Mayans and Aztecs of South Americas -believed the earth had a general shape of a flat cross About 1400 BC Hindu Writing -described the earth as a round disk 200 BC Aristarchus -Reasoned that the earth is round

The Earth is Round

How does the Earth appear to an observer in an open field where no trees or buildings block his view?

Horizon The line where the sky and the ground seem to meet The greatest distance an observer sees on the Earth’s surface. A 1.6 m tall person can see up to 4.5 km away At 2500 m high one can see up to 178 km away

Activity # 1 List at least seven differences in your notebook. What are the possible explanations for the change in scenery?

Evidence that the Earth is Round

Space Photos

Sinking Ship Theory

Altitude of Polaris = Latitude

All other stars will move in a counterclockwise direction but Polaris will stay as it is

Astrolabe

Star Paths Across the Sky

Activity #2 Shadow/s formed Object (identify by number) Egg Kalamansi Coin Jar Cover Ball Can

Lunar Eclipse

True Shape of the Earth Oblate spheroid Poles squished and equator bulges Earth rotates on its axis centripetal force pushes squishes the poles and pushes out in the equator

Apparent Shape Earth appears to be a PERFECT Sphere

Gravity Measurement Weigh more at South Pole – closer Weight less at Equator – farther

Current Findings The Earth is like a lumpy POTATO
