Revolution c. Precession d. Progression 9. Why is there a two day difference in the sidereal and synodic months? a. The Moon speeds up at perigee and slows down at apogee. b. The earth has also revolved around the Sun, so the Moon must “catch up.” c. The sidereal day is four minutes shorter than the solar day and it all adds p d. None of these are correct</p><p>10. What are right ascension and declination a. Analogs of latitude and longitude on Earth’s surface b. A means of specifying stars locations on the celestial sphere c. All of the above d. None of the above 11. A way to measure far away objects by measuring their apparent shift in position is called a. Triangulation b. Trigonometry c. Parallax d. All of the above 12. Seasons on earth occur because a. We are closer to the sun at different times in our orbit causing it to warm b. The earth is spinning on it’s axis causing the day to day changes c. The earth is tilted providing more direct sunlight during certain time of the year d. The sun goes through warming cycles creating warming on Earth 13. From full moon to third quarter moon takes about a week. a. True b. False 14. The apparent angular shift of any object across the distant background when viewed from the two different places is known as precession. a. True b. False 15. Right Ascension is the sky coordinate of an object in the East-West direction. a. True b. False 16. The sun passes through the zodiac constellations a. True b. False 17.
