Across
  1. 3. a type of potential energy when an object is held in its place by gravity
  2. 5. second-largest planet in the solar system that has distinctive rings
  3. 7. occurs once per year and marks the beginning of winter when there will be more nighttime hours than any other day of the year
  4. 9. energy that happens when an object is pulled or stretched
  5. 14. a change from one type of energy to another
  6. 16. planets that are made mostly of gas and very large in size
  7. 17. sometimes called a "dirty snowball" because it is made of rock, dust, and ice; it will have a tail that points away from the sun
  8. 19. material in which electricity can easily move
  9. 22. energy that comes from the nucleus of an atom
  10. 23. large blue planet that rotates on its side, has pale rings, and diamond rain
  11. 24. type of energy stored in the atoms of an object that will be changed as it is used
  12. 27. fourth planet from the sun and may possibly have frozen water; rovers have samples of its soil
  13. 32. twice per month the earth, sun, and moon are at a right angle and this causes a tide with very little tidal movement
  14. 34. the measured amount the actual brightness of a star
  15. 36. tide that happens twice per 24 hour period when the moon has a weaker gravitational pull on the ocean resulting in less movement of the water
  16. 37. the transfer of energy through direct touch
  17. 38. an abject in space that has such strong gravity that not even light can escape
  18. 39. all of the potential and kinetic energy of an object; the total energy
  19. 43. phase when the moon is between the earth and sun and appears completely dark
  20. 44. the ability to do work
  21. 45. a small, hot star that is the left over center of an old star that has "died"
  22. 47. piece of a meteor that has traveled through Earth's atmosphere and struck the planet's surface
  23. 49. occurs twice per year when the sun is directly above the equator and there are equal hours of day and night
  24. 50. eclipse that occurs when the moon is lined up between the sun and the earth
  25. 51. the largest high tide that occurs twice per month because the earth, sun, and moon line up in a straight line and combine gravitational pull
  26. 52. phase when the moon is more than halfway lit by the sun beginning on the right side
  27. 53. large groups of stars, dust, and gas that may contain multiple solar sytems
  28. 54. tide that happens twice per 24 hour period when the moon has a stronger gravitational pull on the ocean resulting in more movement of the water
  29. 55. consists of a sun and the planets that orbit that sun
  30. 56. the measurement of time it takes Earth to make one complete rotation on its axis
Down
  1. 1. known as Earth's twin, has the densest atmosphere made of mostly carbon dioxide and has the hottest surface of any planet
  2. 2. energy cannot be created or destroyed
  3. 4. the average distance between the earth and the sun; approximately 150 kilometers
  4. 6. energy due to heat
  5. 8. planets that are dense and rocky
  6. 10. material in which electricity cannot move easily
  7. 11. energy that is in motion
  8. 12. a redish star that is late in its life cycle and has expanded and grown very large
  9. 13. moon phase when the right half of the moon appears to have light
  10. 15. type of energy due to the movement of electrons
  11. 18. contains all of the known objects in space
  12. 20. a path through which electricity can travel that has a load, energy source, and wires
  13. 21. moon phase where the light on the moon begins to disappear but more than half of the moon is still showing light
  14. 25. occurs once per year and marks the beginning of summer when there will be more daylight hours than any other day of the year
  15. 26. moon phase when the moon is directly opposite the sun and appears completely lit by the sun
  16. 28. eclipse that occurs when the earth's shadow falls on the moon
  17. 29. has a large storm that can be seen known as the Great Red Spot
  18. 30. moon phase when light is beginning to appear on the right side of the moon
  19. 31. half of the moon has light but the light on the moon is slowly disappearing
  20. 33. less than half of the moon has light and it is continuing to have less light in the following lnights
  21. 34. the amount of brightness we see from a star in our galaxy based on its distance from us
  22. 35. the distance light can travel in space in one year
  23. 36. type of energy caused by vibrations of electrically charged particles
  24. 40. only planet known to have liquid water and living organisms
  25. 41. the energy stored in an object
  26. 42. outer planet that had a Great Dark Spot that may have been a giant storm but has now disappeared
  27. 46. small, rocky bodies that orbit around the sun; many are found between Mars and Jupiter
  28. 48. planet closest to the sun
  29. 51. type of energy cause by the vibrations of objects moving through the air
