Earth's moon is 3.844 x 105 km from Earth and has a diameter of 3.76 x 103 km. At what distance from your eye would you have to hold a dime so that it has the same angular diameter as the full moon (that it would cover the moon.)

22Answer: ECopyright 2008 Pearson Education, Inc., publishing as Pearson Addison-Wesley.The angular size of your fist, held at arms length, is about:1 degree10 degrees 5 inches10 inches

23Answer: BCopyright 2008 Pearson Education, Inc., publishing as Pearson Addison-Wesley.The apparent size of the moon in the sky is:About degreeAbout 5 degreesAbout 10 degreesAbout a mileAbout 2000 miles (1/4 the earths diameter)

24Answer: ACopyright 2008 Pearson Education, Inc., publishing as Pearson Addison-Wesley.What makes Polaris a special star?It is the brightest star in the skyIt is always directly overhead, no matter where you areIt is near the axis about which the sky turnsIts azimuth (direction) is always due northC and D

25Answer: ECopyright 2008 Pearson Education, Inc., publishing as Pearson Addison-Wesley.When an astronomer describes the altitude of something in the local sky, he or she means:How high something is in the sky, in units of miles or kilometersHow high something is in the sky, in units of degreesThe direction toward something north, south, east, or west

26Answer: BCopyright 2008 Pearson Education, Inc., publishing as Pearson Addison-Wesley.During the year the Sun appears in front of different groups of stars. What are these called? Circumpolar starsCircumsolar starsThe constellations of the zodiacThe tropical constellationsSolstice stars

27Answer: CCopyright 2008 Pearson Education, Inc., publishing as Pearson Addison-Wesley.When an astronomer describes the azimuth of something in the local sky, he or she means:How high something is in the sky, in units of miles or kilometersHow high something is in the sky, in units of degreesThe direction toward something north, south, east, or west

28Answer: CCopyright 2008 Pearson Education, Inc., publishing as Pearson Addison-Wesley.Why are different stars seen in different seasons?The tilt of the Earths axisStars move during the yearAs the Earth orbits the Sun we see the Sun in front of different constellations Because thats how horoscopes workPrecession

29Answer: CCopyright 2008 Pearson Education, Inc., publishing as Pearson Addison-Wesley.Why are the Moon and planets seen only in the constellations of the zodiac?The planets all revolve in the same direction around the SunThe planets all orbit in nearly the same plane, and the zodiacal constellations are in that plane. The constellations in the zodiac are the oldest, and the planets have been known from ancient timesNone of the above reasons

30Answer: BCopyright 2008 Pearson Education, Inc., publishing as Pearson Addison-Wesley.When it is summer in the United States, in Australia it is:WinterSummerIt is always summer in Australia

31Answer: ACopyright 2008 Pearson Education, Inc., publishing as Pearson Addison-Wesley.What causes the seasons?In summer the (whole) Earth is closer to the SunIn summer the tilt of the Earths axis makes the part of the Earth we are on closer to the SunIn summer the Sun is up for more hoursIn summer the Sun climbs higher in the sky so its rays hit the ground more directlyC and D

32Answer: ECopyright 2008 Pearson Education, Inc., publishing as Pearson Addison-Wesley.If the tilt of the Earths axis to its orbital plane was 40 degrees, instead of 23 , but its distance from the Sun remained the same, what would happen to the seasons?They wouldnt change muchThey would become less extremewinter and summer would be more alikeThey would become more extremewinter colder and summer warmerThe whole Earth would get colderThe whole Earth would get warmer

33Answer: CCopyright 2008 Pearson Education, Inc., publishing as Pearson Addison-Wesley.It was the first star to be cataloged by ancient astronomers.It lies close to the north celestial pole and is therefore very useful for navigation.It is the brightest star in the entire sky.It is the brightest star in the northern sky.It is visible from both the northern and southern hemispheres.What makes the North Star special?

34Answer: BCopyright 2008 Pearson Education, Inc., publishing as Pearson Addison-Wesley.Yes, precession will naturally circularize the Earths orbit.Yes, precession will eventually reduce the Earths axis tilt.Yes, precession will make summers occur at the same time, but in what is now the northern spring and southern fall.Yes, but it would take tens of thousands of years, longer than current human history, for this to occur.No, precession only changes the direction in which the North Pole points, and has nothing to do with the seasons.Because of precession, someday it will be summer everywhere on Earth at the same time.
