2. I. Phases, Eclipses, and Tides
a. The __NEAR__ side of the moon __ALWAYS__ faces the Earth.
b. The __FAR__ side of the moon always faces __AWAY__ the Earth.

3. II. MOTIONS OF THE MOON
a. The moon __REVOLVES__ around the Earth and __ROTATES__ on its own axis.
b. The changing relative positions of the __MOON__, __EARTH__, and __SUN__ cause the phases of the moon, __ECLIPSE__, and tides.
c. The moon __ROTATES__ once on its __AXIS__ in the same mount of time as it __REVOLVES__ around Earth.
Sychronous Rotations of Moon (2:19)

4. III. PHASES OF THE MOON
a. The moon does __NOT__ produce light, instead it __REFLECTS__ light from the __SUN__.
b. You __CAN__ see the moon because of the __REFLECTED__ light from the sun.
c. The different __SHAPES__ of the moon you see from Earth are called __PHASES__.
d. The __PHASES__ of the moon you see depends on how much of the __SUNLIT__ side of the moon faces Earth.
e. The moon goes in a cycle every __29.5__ days.

6. IV. ECLIPSES
a. When the moon’s __SHADOW__ hits Earth or Earth’s shadow hits the moon, an __ECLIPSE__ occurs.
b. When an object in space comes between the __SUN__ and a __THIRD__ object, it casts a __SHADOW__ on that object, causing an __ECLIPSE__.
c. There are __2__ types of eclipses: __SOLAR__ eclipses and __LUNAR__ eclipses.
d. Solar = __SUN__
e. __LUNAR__ = Moon

7. A. When Do Solar Eclipses Occur?
a. A __SOLAR__ eclipse occurs when the __MOON__ passes directly between __EARTH__ and the __SUN_, blocking sunlight from Earth.
b. The __MOON’S__ shadow hits Earth, causing a __SOLAR__ eclipse

8. B. Total Solar Eclipses
a. The __DARKEST__ part of the moon’s shadow is the __UMBRA__
b. During a __TOTAL__ solar eclipse the sky grows __DARK__ and the temperature gets __COLD__.
C. Partial Solar Eclipses
a. The largest part of the __SHADOW__ is called the __PENUMBRA__

9. D. When Do Lunar Eclipses Occur?
a. A __LUNAR__ eclipse occurs at a __FULL__ moon when Earth is directly between the __MOON__ and the __SUN__
b. __LUNAR__ eclipse occurs when the __EARTH__ blocks sunlight from reaching the __MOON__

10. V. TIDES a. The __RISE__ and fall of ocean water is called __TIDES__.
b. The force of __GRAVITY__ pulls the __MOON__ and __EARTH__ toward each other.

11. A. Spring Tides
a. The __GRAVITY__ of the sun and the moon pull In the __SAME__ direction causing a __SPRING__ tide.
b. Spring __TIDES__ occur twice a __MONTH__, at __NEW__ moon and at a __FULL__ moon.
c. Example: 1. __MOON__, __EARTH__, and __SUN__ or __EARTH__, __MOON__, and __SUN__

12. B. NEAP TIDE
a. __NEAP__ tides have the __LEAST__ difference between low and high tides. b. Neap __TIDES__ occur __TWICE__ a month, __1st__ and __3rd__ quarter moons. c. Neap tides occur when the __MOON__ and __SUN__ are at __90 DEGREE__ angles
