Prime Meridian

• This imaginary line separates the East and the West side of the Earth

• zero degree (0°) longitude

13

Tropic of Cancer

• This parallel line marks the farthest point north at which the sun can be seen directly overhead at noon

14

Tropic of Capricorn

• This parallel line marks the farthest point south at which the sun can be seen directly overhead at noon
