Presentation Transcript

  1. MoonSeasonsTides

  2. Orbit- the path that a body follows as it travels around another body in space • Rotation-the spin of a body on its axis • Revolution-one complete trip along the orbit

  3. Rotation of the Earth on its axis

  4. Revolution of the Earth-Moon system around the Sun

  5. Label the Picture A. Rotation C. Orbit B. Revolution

  6. DAY-the time required for Earth to rotate once on its axis It takes 1 year or 365 ¼ days for the Earth to revolve once around the sun The Earth’s rotation is the direct cause of daylight and night It takes the Earth 23 hours and 56 minutes to rotate once on its axis The seasons are caused mainly by the 23.5 tilt of the Earth’s axis

  7. EQUINOX-The time when the sun is directly above the equator • SOLSTICE-the time when the sun is farthest north or south of the equator • March Equinox-Spring begins • June Solstice-Summer begins • September Equinox-Fall begins • December Solstice-Winter begins

  8. Phases of the moon: changes in the moon’s appearance • The moon rotates around the Earth every 27.3 days • We always see the same side of the moon because it rotates on its axis and revolves around the Earth at the same rate.

  9. Phase: the change in the sunlit area of one celestial body as seen from another celestial body. • When the moon revolves around Earth, the sunlight that reflects on the Earth changes too

  10. Waxing: the sunlit part of the moon appears to get larger (growing) • Waning: the sunlit part of the moon appears to get smaller (shrinking) • Gibbous: swollen on one side

  11. Eclipse: the shadow of one celestial body falls on another body • Lunar eclipse: when the Earth comes between the sun and the moon • the shadow of the Earth falls on the moon.

  12. Solar Eclipse: when the moon comes between the Earth and the sun • the shadow of the moon falls on part of the Earth

  13. We don’t see solar and lunar eclipses every month because the moon’s orbit around Earth is tilted with respect to Earth’s orbit around the sun • The moon usually passes above or below Earth’s shadow.

  14. Shade in the Pictures First Quarter= Quarter Moon

  15. Tides: the daily changes in the level of ocean water. • The movement of the Earth, sun, and moon cause the seasons and the phases of the moon. • Tides are influenced by our sun and our moon.

  16. The gravity of the moon pulls on every particle of the Earth. • This is more noticeable with the oceans because liquids move easier than solids. • The moon’s pull is strongest on the part of the Earth directly facing the moon.

  17. The blue line shows the location on Earth represented by the tides shown at the bottom of the image.

  18. High Tides: When part of the ocean is directly facing the moon, the water there bulges toward the moon.

  19. Tidal Range: the difference between levels of ocean water at high and low tide.

  20. Spring Tides: tides with the largest daily tidal range and occur every 14 days • During new and full moons

  21. Neap Tides: tides with the smallest daily tidal range • During the first and third quarters of the moon

  22. Phases of the Moon Demonstrationhttp://www.youtube.com/watch?v=FI2tP8dpwNA • How much of the moon is illuminated? • What part of the moon is illuminated? • What did you notice about the moon’s appearance as we orbited around the moon? • Name the phases of the moon.
