  1. How Does the Moon Affect Earth? 1. Moon Phases 2. Tides 3. Eclipses

  2. Eclipses!

  3. What is an eclipse? An eclipse occurs when one object gets in front of you and another object blocks your view.

  4. Umbra: Darkest Part of Shadow Penumbra:Lightest Part of Shadow

  5. Path of Totality - the path (up to 200 miles wide) that the Moon's shadow traces on the Earth during a total solar eclipse

  6. Solar Eclipse:When the MOON is between the SUN and EARTH. Way to remember:EMS (Earth, Moon, Sun) (you need to call the ems if you stare at an eclipse.

  7. Why not a solar eclipse every month then? Moon Earth 5o Ecliptic Moon’s Orbit Sun Moon's orbit is tilted about 5o with respect to the Earth's orbit (ecliptic), so the shadows usually miss!

  8. Explain this!

  9. Just one total eclipse occurs each year or two. Since each total eclipse is only visible from a very narrow track, it is rare to see one from any single location. You'd have to wait an average of 375 years to see two total eclipses from one place. Of course, the interval between seeing two eclipses from one particular place can be shorter or longer. For instance, the last total eclipse visible from Princeton, NJ was in 1478 and the next is in 2079. That's an interval of 601 years. However, the following total eclipse from Princeton is in 2144, after a period of only 65 years. How often do eclipses happen?

  10. Blue = Total Red = Annular

  11. Solar Eclipse

  12. Lunar Eclipse: When the EARTH is between the SUN and MOON Way to remember:MES( Moon Earth, Sun) (it makes a ‘mes’ of a color when the moon is in an eclipse.)

  14. Tides

  15. What Causes Tides?

  16. Moon’s Gravity! The force of gravity pulls the moon and Earth toward each other.

  17. Gravitational Force

  18. Why is the water pulled to both sides? • Moon pulls on the water first • Then the earth moves slightly towards the moon. • Leaving a bulge of water behind on the other side.

  19. Tides Facts High Tide: • It happens about every 12 hours • This happens twice (2x) a day Low Tide: • It happens about every 12 hours • This happens twice (2x) a day

  20. Hopewell Rocks New Brunswick, Canada

  21. Spring Tide • Occurs twice a month during a New Moon and a Full Moon. • The tides are extra highand extra low.

  22. Neap Tide • Occurs twice a month during 1st quarter and3rd quarter. • There is only a small difference between high and low tide.
