UGA GEOG 1111 Lab midterm All Possible Questions and Answers with complete solution

How far apart is each degree of a parallel? - Answer-Each degree of a parallel is about 69 miles/111 Km apart. Great circles - Answer-Circle around Earth where the circle's center is Earth's center. Shortest distance between 2 points and is curved on maps. Small circle - Answer-Circle center is not the center of the Earth. Projections - Answer-Equations to translate a globe to a flat map. All of them distort direction, distance, shape, and/or area. Standard line - Answer-Line/point the map is based on (usually equator or poles) Cylindrical projection - Answer-Turns latitude and longitude into a rectangular grid. Huge distortion in high latitudes. Planar projection - Answer-Gnomic (all straight lines are great circles). Usually one tangent is located at a pole and the map shows an overhead view from that tangent. Mercator - Answer-Cylindrical (preserves shape, and direction, but distorts area, and distance). Albers equal area - Answer-Preserves area, distorts shape, and distance (conic) Robinson - Answer-Compromise that distorts all properties slightly. Map scale - Answer-Ratio of distance on map to actual distance. Can be stated in words, a fraction, or a graphic.Isolines - Answer-Lines on maps connecting points of identical value. They also connect points of equal elevation Isogons - Answer-Magnetic declinations Contour interval - Answer-Distance in elevation between adjacent contour lines. Index contour - Answer-Thicker line, usually labelled with elevation. Depression on topo maps - Answer-Indicated with a closed contour shape with inward tick marks. Total relief - Answer-Change in elevation between the highest and lowest point on the entire map. Local relief - Answer-Change in elevation in two specified points. Oblique rays - Answer-Rays that shine at an angle (less insolation than direct rays) Tangent rays - Answer-Hit at one point (least amount of insolation) Subsolar point - Answer-Point of most direct insolation. Moves North and South as the Earth revolves around the Sun. When is direct insolation/sub solar point the furthest North? - Answer-At the summer (June) solstice When is direct insolation/sub solar point the furthest South? - Answer-At the Winter (December) solstice When is direct insolation/sub solar point in the middle? - Answer-During the Autumnal, and Vernal solstices.Why is the sun more intense during direct insolation? - Answer-This is because the rays are shining directly onto the Earth at that point, creating more intensity because rays are not being spread out. Temperature - Answer-Measures the average kinetic energy of molecules. Also is a product of insolation. Wind chill - Answer-As wind increases it takes heat away from your body and makes it feel colder. 35.74+.6215T-35.75(V^.16)+.4275T(V^.16) Heat index - Answer-More humidity=higher heat index How are altitude and temperature related? - Answer-Inversely (normal lapse rate is 6.4°C/1000m (3.5°F/1000Ft) How are lines of latitude and temperature related? - Answer-Warmer closer to the equator. Coordinates of Athens - Answer-33.95°N,83.38°W
