CN: The Moon
The moon rotates on its axis. –1 moon day The moon revolves around the earth. –1 moon year. What are the two ways the moon moves in space?
Moon Facts 1 moon day = 1 moon year This causes the same side of the moon to face the earth all the time.
The changing relative positions of the moon, Earth, and sun causes the phases of the moon, eclipses, and tides.
Phases of the Moon The different shapes of the moon you see from the earth are phases.
Why are there phases? The phases of the moon you see depends on how much of the sunlit side of the moon faces Earth.
Solar Eclipse Most of the time the moon travels a little above or below the path of the sunlight that shines on earth.
Umbra= darkest part of the moon’s shadow = total eclipse Penumbra= large part of the moon’s shadow = partial eclipse
Where you live on earth determines if you see a total eclipse, or partial eclipse. P 623 old book

Lunar Eclipse During a lunar eclipse, Earth blocks sunlight from reaching the moon. During which phase of the moon can lunar eclipses only happen? P 480 new book
During which phase of the moon can lunar eclipses only happen?- A Full Moon because the earth is between the moon and the sun
Umbra = Total Lunar Eclipse Unlike a total eclipse, a total lunar eclipse can be seen from anywhere on earth when the moon is visible. The reddish tint happens because the Earth’s atmosphere bends some sunlight toward the moon.
