• Geog 30 1 • Page 1 of 4 KEY Part 1: Isolines The map below shows average January sea -level temperatures in °C and °F. There are eight locations, labeled A -H, that you will reference in this exercise. SAC = 1.50  x 4min/  = 6.00min = 6min 0 sec 1. Determine the average sea -level temperature for the following points in °C a. _______ b. _______ c. _______ d. _______ 2. Determine the average sea -level temperature for the following points in °F e. _______ f. _______ g. _______ h. _______ Isolines + Earth Sun Relations • Geog 30 1 • Page 2 of 4 3. The map below gives the temperature in degrees at 52 different cities. Draw isotherms at 5 ° intervals. The 0° isotherm has already been drawn for you. *Remember, some isolines may extend off of the page, some may be a closed circle on the page, and isolines never touch or cross. • Geog 30 1 • Page 3 of 4 Part Two: Earth -Sun Relations The diagram below shows Earth and the sun on June 21. Use this diagram and information from this week’s reading and lecture to answer the following questions: 1. What is the latitude of the subsolar point? 2. Tangent rays are at what latitude in the Northern Hemisphere? 3. Which hemisph ere is experiencing winter in this diagram? Explain Why. 4. Why does the equator receive equal day and night? 5. If you travel north of the equator, does the day (hours of light in the day) lengthen or shorten? 6. What is day length north of 66.5°N latitude? • Geog 30 1 • Page 4 of 4 Us e the diagram below to draw and label the following items on the December solstice: 1. North and South Poles 2. Equator 3. Tropic of Cancer 4. Tropic of Capricorn 5. Circle of Illumination 6. Artic Circle 7. Antarctic Circle 8. Vertical rays of the sun/ subsolar point 9. Tangent rays of the sun
