  • Transcript

    • 1. The Moon SECTION 28.2
    • 2. 1.) Why doesn’t the moon appear blue like the earth? 2.) Why doesn’t the moon have clouds like earth?
    • 3. Landed on Moon Clip
    • 4. Reaching for Moon
    • 5. Reaching for Moon • most knowledge about moon comes from space explorations by space probes
    • 6. Reaching for Moon • most knowledge about moon comes from space explorations by space probes • Neil Armstrong and Buzz Aldrin first men to step on moon
    • 7. First Steps Clip
    • 8. Lunar Properties
    • 9. Lunar Properties • one of largest moons (compared to size of planet it orbits)
    • 10. Lunar Properties • one of largest moons (compared to size of planet it orbits) • moon relatively further from earth than most moons are from planets they orbit
    • 11. Lunar Properties • one of largest moons (compared to size of planet it orbits) • moon relatively further from earth than most moons are from planets they orbit • solid, rocky body
    • 12. Lunar Properties • one of largest moons (compared to size of planet it orbits) • moon relatively further from earth than most moons are from planets they orbit • solid, rocky body • only large moon among inner planets
    • 13. Lunar Surface
    • 14. Lunar Surface • albedo - amount of sunlight moon’s surface reflects
    • 15. Lunar Surface • albedo - amount of sunlight moon’s surface reflects • very small
    • 16. Lunar Surface • albedo - amount of sunlight moon’s surface reflects • very small • temperatures as high as 127ºC
    • 17. Lunar Surface • albedo - amount of sunlight moon’s surface reflects • very small • temperatures as high as 127ºC • temperatures as low as -173ºC
    • 18. Surface Features • highlands - light in color, mountainous, and heavily covered w/ craters
    • 19. Surface Features • maria - dark, smooth plains • have scattered craters and rilles • rilles - meandering, valley-like structures
    • 20. Surface Features • impact craters - formed when objects from space crashed into lunar surface
    • 21. Surface Features • ejecta - material blasted out during impacts • rays - long trails of ejecta
    • 22. Surface Features
    • 23. Surface Features • Q: Why does moon have craters, while earth has few?
    • 24. Surface Features • Q: Why does moon have craters, while earth has few? • A: Erosion on earth has eliminated traces of all but younger craters; on moon, craters present until one impact covers another
    • 25. History of Moon
    • 26. History of Moon • age b/w 3.8 and 4.6 billion years old
    • 27. History of Moon • age b/w 3.8 and 4.6 billion years old • have regolith b/c of being bombarded heavily by space objects
    • 28. History of Moon • age b/w 3.8 and 4.6 billion years old • have regolith b/c of being bombarded heavily by space objects • regolith - layer of loose, ground-up rock
    • 29. History of Moon • age b/w 3.8 and 4.6 billion years old • have regolith b/c of being bombarded heavily by space objects • regolith - layer of loose, ground-up rock • maria slightly younger than highlands
    • 30. Moon’s Interior
    • 31. Tectonics on Moon?
    • 32. Tectonics on Moon? • Q: Is the moon tectonically active?
    • 33. Tectonics on Moon? • Q: Is the moon tectonically active? • A: Has moonquakes, but theorize that NOT tectonically active b/c no volcanos and no significant magnetic field
    • 34. Capture Theory
    • 35. Capture Theory • as solar system forming, large object ventured too near to forming earth, became trapped by gravitational pull, and formed into moon
    • 36. Capture Theory • as solar system forming, large object ventured too near to forming earth, became trapped by gravitational pull, and formed into moon • something needed to slow down object to be trapped
    • 37. Capture Theory • as solar system forming, large object ventured too near to forming earth, became trapped by gravitational pull, and formed into moon • something needed to slow down object to be trapped • earth and moon composed of very similar materials
    • 38. Simultaneous Formation
    • 39. Simultaneous Formation • moon and earth formed at same time and in same general areas thus materials they are formed from are essentially the same
    • 40. Simultaneous Formation • moon and earth formed at same time and in same general areas thus materials they are formed from are essentially the same • does NOT account for different amounts of iron on earth and moon
    • 41. Impact Theory
    • 42. Impact Theory • moon formed as result of gigantic collision w/ earth by mars sized object when solar system was forming • materials from earth’s outer layers ejected into space and merged together to form moon
