GEOG-120 Lecture Notes - Lecture 2: Farthest North, Antarctic Circle, Torrid Zone
Document Summary
Latitudes are imaginary circles running from east to west on the globe. One example of a latitude is the equator which divides the earth into two equal halves known as hemispheres. Latitudes are also called parallels of latitude as they run parallel to the equator. Latitudes are measured with the unit degree, equator is 0 degrees latitude. Poles are 90 north and 90 south. Each latitude is measured in degrees, minutes, seconds. 1 degree equals 60 minutes, Every point on the surface on the earth has a unique latitude. Equator: divides earth into two equal hemispheres, twice in the year, the sun is visible directly overhead of the equator sep 21, Tropic of capricorn: set of points located 23 degrees south of the equator, december 21, sun seen directly overhead. Arctic circle: marks set of points 66 north of equator, june 21, all point north of this latitude will have 24 hours of daylight.
