Arctic Circle 66.5 degrees north of the equator. Is always cold
Antarctic Circle 66.5 degrees south of the equator
Prime Meridian 0 degrees longitude. Runs north to south. Goes through Greenwhich England.
Longitude Lines that run from N.Pole to the S.Pole. Parallel to the Prime Meridian. 18o lines/degrees to west. 180 lines/degrees to east
Describe mountains Highest landform. At least 2000 feet above sea level
Describe hills Lower than mountains. 500-2000 feet above sea level
Describe plains Large areas of flat or gently rolling land. Less than 1000 feet above sea level
Describe plateaus Raised areas of land. 300-3000 feet above sea level
