Are they parallel to each other? • What are the lines by which we measure longitude called? • What is the name of the central line by which we measure longitude? • Which direction do longitude lines run? Are they parallel to one another? LATITUDE, LONGITUDE AND THE SEASONS • Is the equator an arbitrarily chosen line or does it have some significance pertaining to seasons and great circles? • Is the central meridian by which we measure longitude arbitrarily chosen or does it have some significance pertaining to seasons? • What is the significance of the Tropic of Cancer and Tropic of Capricorn in terms of both the sun’s position in the sky and day length? • What is the significance of the Arctic Circle and the Antarctic Circle in terms of both the sun’s position in the sky and day length? • If you were to be stationed at a South Pole research station for one year, how would day and night be distributed over the course of the year? Why is it that way? GREAT CIRCLES AND SMALL CIRCLES • Does a plane route from Santa Barbara to Hiroshima, Japan (both cities are located at approximately 34º N) that does not stray from the 34 th parallel the quickest route to travel to Hiroshima? Why or why not? Does it follow a Great Circle Route ? • What is the definition of a great circle ?...
