^^Definitions:^^

• Circumference: distance around the circle.
• Diameter: distance across the circle, through its center
• Radius: distance from its center to its edge.
• Latitude lines measure north or south of the equator (0°) splitting the earth into the Northern Hemisphere and Southern Hemisphere.

• Lines of longitude measure east to west of the Prime Meridian 0° to the 180° line. \n @@The@@ @@equator@@ @@is 0 degree latitude.@@

@@It is an imaginary belt that runs halfway point between the North Pole and the South Pole.@@

\

• @@The Prime Meridian (0°) and the 180° line split the earth into the Western Hemisphere and Eastern Hemisphere.@@

\
==The Earth is a sphere.(It is actually an oblate spheroid, slightly larger at the equator than at the poles)==

%%The Earth is slightly flattened from a perfect spherical shape because of%%

1. %%its rotation%%
2. %%the pull of the sun and moon%%
3. %%storms on the sun’s surface%%
4. %%its molten core%%

^^Time Zones/Time And How To Find It^^

• ^^Longitude is based on Earth’s rotation^^
• ^^Earth rotates counterclockwise at 15 degrees/hr^^
• ^^360 degrees/24hrs = 15 degrees/hr^^
• ^^There are 24 time zones in the world- one for every line of longitude^^
• ^^People on the same line of longitude have the same^^ ^^solar time^^
• ^^When you go west you subtract time and when you go east you add time^^
• Latitude and Longitude is measures in degrees- degrees can divided into minutes( ’ )There are 60 minutes in each degree.

@@Polaris (latitude)@@

• @@North Star- found in the little dipper@@
• @@Latitude = altitude of Polaris@@
• @@Can only be seen in the Northern Hemisphere@@
