    A crystalline solid formed from the cooling and hardening of magma and made up of more than one mineral
  35. What are vesicles?
    Gas pockets
  36. What is a sedimentary rock?
    Sediments that have been cemented together
  37. What is a metamorphic rock?
    Rock that has been made through intense pressure and heat
  38. What is rock gypsum?

  44. Why is the north pole cold?
    Low angle of insolation
  45. How can climate change slowly?
    Through differences in precision and the movement of plates

  47. What is the temperature of the Earth’s mantle? (give a range)
    100C-5000C

  55. Is Betelgeuse a blue giant?
    No
  56. Does Betelgeuse have a high luminosity?
    Yes
  57. What is a redshift?
    When light waves are moving away from you
  58. What is a blueshift?
    When light waves are moving towards you
  59. What does wave length have to do with redshifts and blueshifts?
    Wave lengths get longer with a redshift and get shorter with a blueshift

    Mid ocean ridges
  61. What features can we find at convergenc plate boundaries?
    Subduction zones and trenches
  62. How do we calssify rocks?
    Through texture, rock formation, particle size, chemical make up

    It increases
  70.  How can you use patterns to help classify and organize things like rocks and minerals?
    By seeing how patterns form, you can classify rocks based on their physical properties.  This enables scientists to study them better since they are grouped according to those properties
  71. Why would studying events and their causes help scientists?
    It allows scientists to predict future events and how to better prepare the public.  It also allows them to recognize things that are unusual.
  72. Why should I worry about scaling things down so I can understand them?
    It allows us to better study things that are either normally to small to see or too large to comprehend. 
  73. Give an example of how nature likes to keep itself in balance
    The mid ocean ridge introduces new rock while the subduction zones recycle old ocean floor.  The cycle continues, keeping the age of the ocean crust fairly young when compared to the continent.
  74. Think about density in space.  Are they related? How?
    Density is related to mass and volume.  The more dense an object is, the more gravitational pull it has, because of the ratio of mass to volume.

In order to calculate what you need on your final to get the final grade you want, use the following excel functions to figure it out.  

MP stands for Marking Period. You simply need to enter your three marking period grades and the final grade you want.  The program will calculate not only your weighted marking period grades but also the weighted final exam grade.  Your final semester grade is calculated by adding your weighted marking period grade and your weighted final exam grade together.  ​
