Questions 1-8 are relate to concepts in Chapter 15 Questions 9-16 are relate to concepts in Chapter 16 1) What are the minimum and maximum values for latitude and longitude? (2pts) - The minimum latitude is 0 degrees and the maximum latitude it 90 degrees. - The minimum longitude is 0 degrees and the maximum longitude is 180 degrees. 2) Are any meridians great circles? Explain (1.5 pts) - No, because meridians are ½ of the great circle. 3) Are any parallels great circles? Explain (1.5pts) - Only one parallel is a great circle and it is the equator. 4) At what latitude is the noon Sun directly overhead on each of the following days: (2pts – one each answer) a) The beginning of our summer - The latitude that is directly overhead the noon Sun is 23 ½. b) The beginning of our winter - The latitude that is directly overhead the noon Sun is 23 ½. c) The beginning of spring - The latitude that is directly overhead the noon Sun is directly over the equator. d) The beginning of fall - The latitude that is directly overhead the noon Sun is directly over the equator. 5) What is the number of latitude degrees between (2pts) a) Place A (20°N, and 75 ° W) and place B (30°S, and 75 ° W) - The number of latitude degrees between Place A and Place B is 135 degrees. 6) What is the number of nautical miles between Place A and Place B in the previous problem? (2pts) - The number of nautical miles between Place A and Place B is 8100 nautical miles.

(2pts) - The latitude and longitude of the point on Earth that is opposite Sao Paulo, Brazil is -24 degrees North and -133 degrees East. 8) Determine the month and day when the Sun is at minimum altitude for an observer in Washington, D. C. (39°N). What is the altitude of the Sun at this time? (2pts) - The month and day when the Sun is at minimum altitude for an observer in Washington, D.C. is on December 22. 9) List the objects that make up our solar system? (2pts) - The objects that make up our solar system are the Sun, eight planets with more than 170 satellites (moons), four dwarf planets, thousands of asteroids, vast number of comets and meteoroids, as well interplanetary dust particles, gases, and a solar wind composed of charged particles. 10) At what location in a planet’s orbit around the Sun is that planet moving at its slowest speed ? (1pts) a) What is the proper term for this location? (1pts) - The speed is the slowest when the planets are farthest from the Sun this is called Aphelion. 11) At what location in a planet’s orbit around the Sun is that planet moving at its the fastest speed? (1pts) a) What is the proper term for this location? (1pts) - The speed is the fastest when the planets are closest to the Sun this is called Perihelion. 12) What are the major distinctions between the Jovian planets and the terrestrial planets? (1pts) a) List the Jovian planets (1pts) - Jovian planets are strong magnetic fields, have many moons and rings, and are very distant from the Sun, with orbits far apart from one another, composed mainly of hydrogen, and helium gases, have relatively low densities. Terrestrial planets are relatively small in size and mass, rocky material and metals, relatively dense and have solid surface. The Jovian planets are Jupiter, Saturn, Uranus, and Neptune. 13) Why is the orbit of Uranus considered “odd” or peculiar? (1pts) - The orbit of Uranus is considered “odd” or peculiar because Uranus orbits at a tilt of 98 degree from the perpendicular. 14) What are dwarf planets? (2pts) - Dwarf planets are a new class of planets. a) How many are in our solar system (according to the textbook) - There are five dwarf planets in our solar system. b) Name at least 3 of them
