1. Moon Notes
Chapter 12

2. The Moon
The positions of the moon, Earth, and sun causes the phases of the moon, eclipses, and tides.

3. Rotation vs. Revolution
A “day” and a “year” are the same length on the moon.
One day = 1 rotation of the moon= 29.5 earth days

4. Dark Side of the Moon The ‘dark side’ is the side we never see.
The moons whole set of phases occurs in 29.5 days

5. Phases of the moon
Depends on how much of the sunlit side of the moon faces the Earth

6. Eclipses occur when….
The moons shadow hits Earth or Earth’s shadow hits the moon
There are ‘solar’ eclipses, and ‘lunar’ eclipses

7. Solar Eclipse Occurs when the moons shadow falls on the Earth.
Sun, moon and Earth aligned

8. Lunar eclipses occur when the earth’s shadow falls on the moon

9. View of Solar Eclipse

10. Tides
The tides are caused mainly by differences in how much the moon’s gravity pulls on different parts of the Earth

11. High vs. Low Tide Tides occur in a daily cycle.
As the Earth rotates on its axis, any point on Earth goes through a cycle of high tide, low tide, high tide, low tide.
The moon’s gravity causes high tide on the side closest to the moon,
Low tide occurs when that part of the Earth is at a 90 degree angle to the moon.
