  1. Hello, My name is juliana.
  2. Today I will be having you with question eight.
  3. Okay. The first thing we have to do is read the question three times
  4. I'm going to read it to you three times
  5. the following question has two parts first answer.
  6. A then answer per p part of the picture shows the positions of four stars
  7. relevant
  8. to Earth's access and equator.
  9. When viewed from the Northern hemisphere which start appears to stay
  10. in the same place in the sky throughout the night,
  11. What causes some stars to appear to stay in the same
  12. place while other stars appear to move across the sky.
  13. You're focusing on that
  14. And late two more times.
  15. The following question has two parts first answer, part eight, then answered. Part
  16. part of the picture shows the positions of
  17. four stars relevant to Earth's axis in equator.
  18. What when viewed from the
  19. northern hemisphere,
  20. which star appears to stay in the same place and described the rub
  21. the night
  22. party?
  23. What causes some stories to appear to stay in the
  24. same place while other stories appear to move across the sky
  25. through us. And only
  26. the following question has two parts. The first answer.
  27. Primary then answer part B.
  28. The picture shows
  29. the decision of four stars relevant to Earth's access in equator
  30. When viewed from the northern hemisphere,
  31. which star appears to say in the same place in the sky throughout the night
  32. property what causes some starts to appear in
  33. do you stay in the same place while other stars
  34. appear to move across the sky throughout a single night.
  35. Okay, so now we're going to look at the diagram.
  36. So this is the diagram that you saw?
  37. And
  38. the question it was right above
  39. part a
  40. part of this question.
  41. As you can see
  42. there were stars with numbers on them
  43. and they're just start with the numbers on the
  44. the stars.
  45. The stars are the four stars.
  46. We have to look at to understand the first part of this question.
  47. So now what is the axis pointing to
  48. wait? What is an access
  49. and access is an imaginary line that's listened to
  50. the middle of the Earth.
  51. So when summer in access is an imaginary line that goes down the middle of the Earth.
  52. So that is
  53. the access That's it's that's the blue one was going down
  54. now, what is the line splitting the center of the earth?
  55. So
  56. if you look back here, you see that, what on earth's going across?
  57. That's what we're going to talk about.
  58. That line is the equator.
  59. So, I got a close up picture right here.
  60. Okay,
  61. right now we do not need to worry about the creator. We have to worry about the Acts. So
  62. to review it.
  63. Um that line,
  64. the blue line down there is the access.
  65. All right now let's go over what a star is
  66. A star is
  67. mostly just rock and gas.
  68. Okay, now let's look at part of the question,
  69. I'm going to read it to you once the following question has two parts First
  70. Aid then party. All right. The picture shows took
  71. positions of four stars relevant to Earth's axis? Any equator.
  72. When do the Northern hemisphere, which still
  73. exist in the same place and described throughout the night.
  74. So the first thing we have to do is look at the star
  75. that the access is way too.
  76. So you see that blue line kind of follow it and
  77. you can pause the video to try to figure it out.
  78. All right. So, the access is planning to star number two.
  79. So as you can see here,
  80. that would be your answer then to say to what the access is pointing to.
  81. Good job. We are almost done. I know this is a little longer
  82. now part B of the question
  83. what causes Son starts to appear to stay in the same place while
  84. other stars appear to move across the sky throughout a single magnet.
  85. So you can kind of read the options to yourself.
  86. You can pause this video to raise the options to yourself in your head.
  87. So, this part of the question a little bit harder.
  88. Um, I'll read it again to you and I will also review the options
  89. heartbeat when across the sun starts to appear to stay in the same place
  90. while other stars appear to move across the sky throughout a single night.
  91. Eight Earth rotates on its axis.
  92. The Earth revolves around the sun.
  93. So you have with the Earth faces away from the sun at all times.
  94. The length of that time change changes as the seasons change.
  95. So why does this start with the two? And it looks like it's staying in the same spot?
  96. Well remember remember when we were talking about the access,
  97. so when it spins the stars look like they're moving.
  98. So it is because the Earth spins on its access. So that was our answer to part B.
  99. So thank you for watching us. I know it was long, but I hope you understand that.
  100. Thank you.
