  • 13. Moon Vocabulary
    • Albedo – amount of sunlight the surface reflects
    • Highlands – light in color, mountains
    • Impact craters – craters formed when space objects hit the moon.
    • Rilles – meandering valleys
  • 14.

  • 16. Moon Formation
  • 17. Sun – Earth – Moon Systems
  • 18.  
  • 19. Earth’s Rotation
  • 20. Effects of Earth’s Tilt
  • 21. Summer Solstice
    • Suns maximum altitude in the sky in the Northern Hemisphere
    • Sun directly overhead at the Tropic of Cancer (23.5 North latitude)
  • 22. Winter Solstice
    • Northern Hemisphere is tilted away from the Sun.
    • Directly overhead at the Tropic of Capricorn (23.5 South latitude)
  • 23. Autumn Equinox
    • The length of the day and night are equal for both the northern and southern hemisphere.
  • 24. Vernal Equinox
    • Also equal night and day.

  • 32. Early planetary theory
    • Early scientist thought that everything revolved around the Earth.
  • 33. Kepler’s First Law
  • 34. Retrograde Motion
  • 35. The Planets
  • 36. Mercury
    • No Atmosphere
    • Surface Temperature: 700K
    • Similar to Moon’s surface
    • Slow spin, small size, high density
    • Nickel-iron core
  • 37.  
  • 38. Venus
    • Brightest planet
    • Cloudy
    • One day is 243 Earth days
    • Sun rises in west and set in east (just opposite of Earth)
    • Similar to earth in physical properties
    • Hottest planet.
    • Greenhouse gas effect present.
    • Smooth
  • 39.  
  • 40. Earth
  • 41. Jupiter
    • Largest planet (11 times larger than earth)
    • Shortest day in solar system
    • Large red spots

  • 46. Uranus
    • Discovered accidentally in 1781
    • Many moons and 10 rings (Titania and Oberon)
    • Fluid except for small solid core
    • Sits on side so long nights and long days
  • 47.  
  • 48.  
  • 49. Neptune
    • Predicted to exist before discovered

  • 51. Pluto
    • Small size
    • Does not have characteristics of any of the other planets
    • North pole points south
    • Satellite (Charon) which orbits around it
    • More like a moon than a planet
  • 52.

  • 54. Planets Project
    • Each one of you will be given a planet.
    • We will spend one class in the library researching your planet
    • You will take that information and write a children's book. (Kindergarten to 2 nd grade level.)
    • Books must be at least 10 pages and must be illustrated.
    • They are due Monday, November 13, 2006.
  • 55. How was the solar system formed?
  • 56. Condensation Theory: Made from Solar Nebula
  • 57. From part of the sun:
  • 58. Big Bang Theory: Supernova exploded -- particles rotated and combined to form stars and planets
  • 59. Osiris
    • Oxygen and carbon found on planet outside our solar system
  • 60. Asteroids
  • 61. Meteor
  • 62. Meteorite
