Where is the Prime Meridian located? is the meridian (line of longitude ) at which longitude is defined to be 0°. Passes through the old Royal Observatory at Greenwich, England (page 17) 4. Given the ratio 1:500,000, do you think that this represents a small scale map or a large scale map? Large scale (1:2400 > x) 5. What about 1: 24,000? Small scale (1:3,168,000 – 1:250,000) Medium: (1:125000- 1:63,360) 6. If you were standing at 20° N latitude, what latitudinal geographic zone would you be in? ( Artic: 66.5° N to North Pole Subartic 55°N to 66.5°N Midlatitude: 35°N to 55°N Subtripocal 23.5°N to 35°N Equatorial and tropical 23.5°N to 23.5°S Subtropical 23.5°S to 35°S Midlatitude 35°S to 55°S Subantartic 55°S to 66.5° S Antartic 66.5°S to South Pole 7. What about 60° N latitude? (know your latitudinal geographic zones generally) 8. What tool did sailors historically need to use to determine their longitude? 9. Does a Mercator Projection map distort high latitudes or low latitudes? Cylindrical projection, true shape projection with meridians appearing as equally spaced straight lines and parallels appearing as straight lines that are spaced closer to the equator. Poles are infinitely stretched. Of Midlatitude and poleward land masses. 10. What shape is the earth? Oval, equator is buldged Solar Energy to Earth and the Seasons Identification Perihelion orbits around the sun: Aphelion orbits around the sun Subsolar point 48, 51 55 56: place receiving maximum insolation is the point where insolation rays are perpendicular to the survace Insolation 48 90, 118 radiation arriving at Earth’s atmosphere and surface.
