  1. map
    representation of an area or place
  2. elavation
    the height above sea level
  3. planetary system
    star and all of the planets moons and other material that orbit the star
  4. point of view
    a term used to describe the position from which an observation is made
  5. location
    place described in terms of other objects around them
  6. Circle all the words in the list below that identify a luminous source of light in our solar system
    a star the moon the sun Earth Venus Anasteroid a comet
    a star the sun
  7. which direction does earth rotate
    • west to east
    • left to right
    • counterclock wise
  8. Calculate local noon if sunrise is at 7:10 am and sunset is at 6:42pm
    local noon is at 12:56
  9. Explain how it can be 2pm in washignton d.c. on the east coast of the U.S. when it is 11am in seattle on the west coast of the U.S.
    The sun rises in the east coast first so it's morning there 3hours before its morning in the west coast this means there's a 3hour difference so 11am to 2pm is a 3hour difference
  10. If it is 1am on the east coast of the us what time is it on the west coast
    10:00pm
  11. if it is 1am on the west coast of the us wjat time is it on the east coast
    4am
  12. TorF craters are the round holes or circles you see on the surface of the moon if f explain correctly
    t
  13. t or f mare means ocean and is the name given to large bodies of water on the moon if f eplain correctly
    f mare means ocean and its the dark parts of the moon and that area is usually flat
  14. t or f highlands are light colored areas on the moon with lots of rough mountains if f explain correctly
    t
  15. t or f highlands on the moon appear to have fewer craters then do the maria if f explain correctly
    f highlands on the moon appear to have more craters than the mare
  16. t or f white lines that extend out in all directions from a crater are called rilles if f explain correctly
    white lines that extend out in all directions from a crater are called rays
  17. t or f structers that look like ditches channels canyons and streams are called rays if f explain correctly
    f structures that look like ditches channels canyons and streams are called rilles
  18. if one area of the moon has relativly few craters explain why this might be
    there probably in the mare section the reason there's probably not as many craters is because these were formed from lava and are not impact craters also a mare is a flat dark place
  19. at position e there are some mountains explian why these might result from an impact crater
    these result from an impact crater because as a crater is hitting the moon debris expel from the bottom and go flying somewhere else which creates other craters. As the crater hits though it makes the edge rise creating mountains but not only around the edge but around the whole crater
  20. the largest flooded crater is archimedes. Archimedes is 83km in diameter. What is the actual diameter if Eratosthenes the complex crater in the lower left corner of the photo eratosthenes is 1.8 in
    archimedes is 2.5
    actual diameter of erat. is 59.76km
  21. WHat is the shortest distance between arch. and erat. scale is 1cm=33.2km distance in cm is 13.1cm
    shortest distance is 434.92km
  22. how aare night and day the same on moon and earth
    both have day and night half of the earth is always in daylight and half is in darkness just like the moon
  23. how are day and night von the moon and earth different
    the length one day onearth is 24hours and one day on moon is 28 days
  24. explain the mineral composition of rocks collected on the moon in terms of density
    • Every rock collected on the moon has different density. Different density= different material
    • rocks that are darker tend to have a higher density rocks that are lighter tend to have a lower density so mars are denser than highlands also minerals found in the center of the moon are very dense because when the moon was being formed it was molten and denser rocks sink to the center
  25. tell the density
    norite-52grams-18vol
    troctolite-75mass-22vol.
    ilmenite-102mass-22vol.
    anorthosite-60mass-20vol.
    • 1. 2.89
    • 2. 3.41
    • 3. 4.64
    • 4. 3
  26. the dominent theory of the origin of the moon suggests
    a massive impact between earth and a planetoid produced a large quantity of ejecta some of which became the moon
  27. what keeps the moon from flying off into space
    earths gravitaional pull
