  1. MID-TERM REVIEW 2013-2014 Astronomy

  2. 1. HOW DOES THE Earth move in space? Revolution

  3. 1. HOW DOES THE Earth move in space? Rotation • Spins on its axis • Takes 24 hours

  4. 2. What causes the seasons? • The TILT of the Earth!!!! • animation

  5. Matching 3. B • D • G • E or F • E OR F • A • C

  6. 10. WHAT DETERMINES THE STRENGTH OF THE FORCE OF GRAVITY BETWEEN 2 OBJECTS? • Distance between objects…the closer they are the stronger the pull of gravity • Size of the objects…the bigger they are they more the pull of gravity

  7. 11. What two factors combine to keep the Moon and the Earth in orbit? • Gravity—pulling it towards the Sun • Inertia-objects in motion stay in motion

  8. Matching • B • D • A • F • C • E • G

  9. 19. WHAT CAUSES THE PHASES OF THE MOON? • Phases depend on how much of the lit side of the moon we see on Earth • Takes 28-29 days to complete the cycle…about a month

  10. 20. Label the Phases of the Moon

  11. 21. What are solar and Lunar eclipses? • Solar Eclipse

  12. 21. What are solar and Lunar eclipses? • Lunar Eclipse

  13. 22. What Causes the tides? • The Alignment of the Sun, moon, and the Earth. • The Moon has a stronger pull because it is so close to the Earth • Spring Tide Neap tide

  14. Matching • B • G • A • E • C • D • F

  15. 30. What objects make up the solar system? • Sun • Moon • 8 Planets • Asteroids, comets, meteroids

  16. 31. What are the layers of the Sun’s interior?

  17. 32. What characteristics do the inner planets have in common? • Small • Solid or rocky • No rings • Few or no moons

  18. 33. What characteristics do the outer planets have in common? • HUGE • Made out of gas • Many rings • Many, many moons

  19. 34. What are the characteristics of comets? • Ice, dust and rocky particles caught in an orbit around the Sun

  20. 35. Where are the most asteroids found? • In the asteroid belt between the inner and outer planets

  21. 36. What are meteoroids and how do they form? • Chunks of rock or dust in space • They typically come from asteroids or comets • They do not have a set orbit • Meteoroid  Meteor  Meteorite

  22. 37. What is a star system? • Stars that are members of groups of 2 or more stars

  23. 38. What are the major Types of Galaxies? • Spiral, Elliptical, Irregular • They are groups of stars bound together by Gravity • We live in a spiral Galaxy called the Milky Way

  24. Milky Way-Top View Sun s location

  25. Milky Way-Side View Sun’s location

  26. 39. What is the Big Bang Theory? • Enormous explosion that created our universe • Continues to expand today

  27. 40. How did the solar system form? • About 5 billion years ago a cloud of dust collapsed to form the Sun and the planets • The planets formation is called the Dust Cloud Theory

  28. 41. What do astronomers predict about the future of the universe? • Continue to expand further and further apart • Expand to a point, then snap back like a rubber band OR

  29. H-r diagram

  30. Lunar Solar What type of eclipse is the picture showing?

  31. First quarter Third quarter Full Moon New moon What phase of the moon is located at “A” A

  32. 1 year 6 months 1 day 12 hours Approximately how long does it take Earth to move from position A to position B?

  33. summer autumn winter spring Which season is occurring in the Northern Hemisphere?

  34. distance between Earth and the Moon speed of the Moon in its orbit position of the Moon in its orbit position of the observer on Earth A student drew the pictures below to show how the Moon looked from Earth over a two-week period. The differences shown in the student’s drawings are mostly due to the changing

  35. The Sun and the Moon have the same diameter. The Moon is larger in diameter and farther from Earth than the Sun. The Moon is smaller in diameter and is closer to Earth than the Sun. The Sun and the Moon are the same distance from Earth. Which statement best explains why the Sun and the Moon appear to be about the same size in the sky?

  36. rotating on its axis revolving around the Sun much smaller than the Sun tilted on its axis The Sun appears to move across the sky during the day. The best explanation for this apparent motion is that Earth is …

  37. A day A week A month A year Approximately how long does it take to cycle from one new Moon to the next new Moon?

  38. August 7 August 14 August 21 August 28 The diagram below shows four Moon phases observed during July. On which date would the next Full Moon occur?
