  1. Rotation & RevolutionHow does the movement of the sun, earth, and moon relate to days, lunar cycles, and years?

  2. Orbit – the path the earth takes to travel around the sun. orbit sun

  3. ROTATION

  4. Rotation – the Earth spinning on its axis. earth

  5. Period of Rotation –The amount of time it takes for this rotation to happen: one day (24 hours)!

  6. Rotation A=Axis

  7. REVOLUTION

  8. Revolution - the motion of the Earth orbiting around the sun. • sun earth

  9. Period of Revolution – the amount of time it takes for an object to orbit around the sun once: One year (365 Days). earth sun

  10. Every planet revolves around the Sun! The closer you get to the sun the shorter the revolution/orbit. Shorter years Longer years

  13. Review QUESTIONS:

  14. What does each letter represent? C • earth A sun sun B

  15. Rotation or Revolution?

  16. Rotation or Revolution?

  17. Rotation or Revolution?

  18. SOLAR & Lunar ECLIPSE Objective: What is the difference between a solar and a lunar eclipse?

  19. North Pole Sun South Pole Solar Eclipse Details Moon A solar eclipse occurs when the moon comes between the Earth and the sun. MMS= Moon Middle Solar

  20. Partial Solar Eclipse • The moon passes between Earth and the Sun. The moon covers part of the sun.

  21. Total Solar Eclipse • Moon passes directly between Earth and the Sun. Moon blocks our view of the Sun. Only the Sun’s corona is visible.

  22. Annular Solar Eclipse • Moon passes directly between Earth and the Sun. The moon appears smaller than in a total eclipse because it is further from the earth.

  23. LUNAR ECLIPSE

  24. Earth Sun Moon’s Path A Lunar Eclipse During a Lunar Eclipse the Earth’s shadow falls on the moon and the moon can look RED!!! Moon

  25. The moon becomes a blood red color during a total lunar eclipse. No wonder that ancient cultures feared the appearance of the moon during a lunar eclipse.

  26. Review Questions:

  27. Answer

  28. What type of eclipse?

  29. Earth’s axis goes directly through _______. • The north and south poles • The sun • The common center of mass

  30. When we watch the sun rise and set we are actually experiencing Earth’s ____. • Rotation on its axis • Revolution around the sun • Revolution around the moon

  31. Fewer people can see total solar eclipses than lunar eclipses because A) the Moon casts a smaller shadow than Earth does B) solar eclipses almost never happen C) only people at the South Pole can see solar eclipses

  32. When Earth is directly in between the Sun and the Moon, people on Earth experience a __________. A) lunar eclipse B) solar eclipse C) half Moon

  33. When the Moon is directly in between the Sun and Earth, some people on Earth may experience a __________. A) solstice B) lunar eclipse C) solar eclipse

  34. A lunar eclipse occurs when ___. A) the Sun passes into the Earth’s shadow B) the Earth passes into the Moon’s shadow C) the Moon passes into Earth’s shadow D) the Moon passes into the Sun’s shadow

  35. When a lunar eclipse occurs what happens to the Moon? A) It vanishes from existence, to be recalled on the whim of a magician. B) It is covered in shadow and hidden from view for a brief time. C) It becomes extraordinarily bright. D) Nothing happens to it.

  36. When a solar eclipse occurs, what happens to the Moon? A) It falls into the Earth’s shadow. B) It moves between the Earth and the Sun, causing a part of the Earth to fall into its shadow. C) It lies outside of a straight line connecting the Earth and Sun. D) It disappears from view.
