  1. The Moon Phases and Eclipses

  2. Key Concepts • We always see the SAME SIDE of the Moon because the moon orbits the Earth and rotates on its axis with EXACTLY the same period • Phases of the Moon: New, Waxing Crescent, Quarter, Waxing Gibbous, Full, Waning Gibbous, Quarter, Waning Crescent, New, etc. • Eclipses: Penumbra and Umbra • Solar Eclipses: Total, Partial, and Annular • Saros Cycle

  3. The Moon orbits the Earth once every 29 ½ days and the Moon rotates on its axis once every 29 ½ days therefore we always see the SAME SIDE of the Moon.

  4. The Moon appears to go through a series of PHASES during each month: new moon, crescent, gibbous, full, gibbous, crescent, new. Phases of the Moon youtube.com rap. Phases of the Moon Animation Phases of the Moon Applet Animation

  5. Lunar Eclipse = Earth's shadow falls on the Moon Solar Eclipse = Moon's shadow falls on the Earth Basic Geometry Cause of Eclipse Animation Why don’t we get a solar or lunar eclipse every month? Animation of the Moon’s orbit

  6. MORE LINKS! Solar Eclipses: total, partial, annular Path of Eclipses on Earth Eclipse Seasons (Saros Cycle)

  7. Examples of Beautiful Eclipses!

  8. Why Are There Seasons?? http://livewithpurposecoaching.com/wp-content/uploads/2010/04/seasons1.jpg

  9. Reasons: NOT NOT NOT because the Earth is closer to the Sun in summer and farther in winter.  OK???? 1. The Earth's axis is tilted, and during the year the axis points basically in the same direction (except for tiny motion or precession).

  10. More Reasons: • 2. During summer in the northern hemisphere, the northern part of the Earth points TOWARDS the Sun. • sunlight is direct, more intense, heats the earth • days are longer • sunlight has less atmosphere to go through so is more effective in warming the ground • and vise versa for winter. 3.When it's summerin the northern hemisphere, it's winter in the southern hemisphere, and vise versa. 4.Key Terms: Summer Solstice, Winter Solstice, Equinox
