  1. Chapter 9 Review

  2. The time required for a planet to rotate on its axis one complete time is known as what? day

  3. Periodic rise and fall of the water level in the oceans and other large bodies of water are known as what? Tides

  4. When the shadow of one celestial (in space) body falls upon another celestial body it is called an: Eclipse

  5. The path that a body follows as it travels around another body in space is known as what? Orbit

  6. The two days per year where neither pole is tilted more toward the sun are known as what? Equinoxes

  7. The movement of a body traveling around another body in space is called: revolution

  8. Who was the German astronomer that developed the laws of planetary motion? Johannes Kepler

  9. The scientific law that states that planets move around the sun in elliptical pathsis called: Kepler’s First Law of Planetary Motion

  10. “The force of gravity depends on the product of the masses (m x m), divided by the square of the distance between them (d2),” is known as what scientific law? Newton’s Law of Universal Gravitation

  11. What is Kepler’s Second Law of Planetary Motion planets move faster the closer they are to the sun

  12. What force causes the tides to rise and fall each day? Gravitational pull of the Moon

  13. The two days every year where there are exactly the same number of daylight hours as dark are known as what? Equinoxes

  14. “The time it takes a planet to orbit the sun is directly proportional to the distance the planet is from the sun” is known as what scientific law? Kepler’s Third Law of Planetary Motion

  15. The change in sunlit area of one celestial body (in our case, the moon) as seen from another celestial body is called what? phases

  16. The two days per year where the axis of the Earth leans towards (or away from) the sun the most. Solstices

  17. If the mass of the earth were doubled, how would that affect your weight? Your weight would double

  18. The difference in levels of ocean water between high and low tides is known as what? Tidal Range

  19. What kind of eclipse happens when the shadow of the moon falls on the Earth? Solar Eclipse

  20. When moon phases are waning, the sunlit part of the moon is in the process of getting ______________. smaller

  21. The two days per year where we have either the most amount of sunlight or the least amount of sunlight are called what? Solstices

  22. What kind of eclipse happens when sections of the sunlit moon are blocked out by the shadow of the earth Lunar Eclipse

  23. Name a season of the year when an equinox might occur. Spring or Fall

  24. Tides of increased tidal range which occur when the SUN-EARTH-MOON are in a straight line are known as what? Spring Tides

  25. When moon phases are __________, the sunlit part of the moon is in the process of getting larger Waxing

  26. Tides of decreased tidal range which occur when the SUN-EARTH-MOON form a 900 angle are known as what? Neap Tides

  27. Because the time required for one rotation of the Earth and one revolution of the moon are ___________, we always see the same side of the moon. equal

  28. Name a season of the year when a solstice might occur. Winter or summer

  29. What fact about the Earth’s axis causes there to be changing seasons in many places on the earth? 23.5 0 tilt

  30. If the distance between two bodies in space increases, what happens to the force of gravity between them? decreases

  31. When the north pole is pointing towards the sun, what season is it in California? Summer

  32. Toss Up Questions

  33. What kind of tide has the highest low tide? Neap tides

  34. Why don’t we see lunar and solar eclipses every month? The orbit of the moon is tilted 50 off that of the Earth

  35. What kind of tide has the highest high tide? Spring tides

  36. A closed curve in which the sum of the distances from the edge of the curve to two points inside the curve are always equal is known as what? Ellipse

  37. What kind of tide has the lowest high tide? Neap tides

  38. What kind of tide has the lowest low tide? Spring tides

  39. What kind of eclipse occurs when most of the sun is blocked out by the moon but the moon appears to not be large enough to block out the entire sun? Annular Solar Eclipse
