2. Phases of the Moon Waxing – more of Moon’s lighted side becomes visible Waning – visible lighted side of Moon shrinks

3. Phases of the Moon New Moon – Moon is between Sun and Earth, invisible to us Waxing Crescent Moon – Sliver of moon, follows new moon

4. Phases of the Moon 1 st Quarter Moon – H alf of moon visible, follows new moon Waxing Gibbous Moon – ¾ of moon visible, follows new moon

5. Phases of the Moon Full Moon – Completely visible, Earth is between Sun and Moon Waning Gibbous Moon – ¾ of Moon, follows full moon

6. Phases of the Moon 3 rd Quarter Moon – H alf of Moon, after full moon Waning Crescent Moon – Sliver of moon, after full moon

7. Moon’s Rotation Moons rotation upon its axis is same as its orbit around Earth Earth sees the same face of the moon

8. Eclipses The partial or total blocking of one object in space by another Involves sun, moon and earth Two types: Solar and Lunar Umbra is darkest part of shadow Penumbra is the larger part of shadow

9. Umbra and Penumbra

10. Solar Eclipse Moon blocks view of sun Occurs during New moon

11. Lunar Eclipse Earth casts shadow on the moon Occurs at a full moon

12. Tides Rise and fall of ocean water Occurs every 12.5 hours –6 hours rising –6 hours receding Tides are caused mainly by Moons gravitational pull.

13. Tide Cycle 2 high tides and 2 low tides Due to gravitational pull of moon Due to phases of moon, variation in tides –Spring: Increased difference between high and low tides –Neap: Minimal difference high and low tides
