Intro to the moono The moon does not produce its own
light - we see the moon because it is reflecting light from the Sun.

Moon Phases
o Like Earth, the moon moves through space in 2 ways:
o The Moon revolves around the Earth in 27.3 days
o The Moon also rotates on its own axis in 27.3 days
![Page 4: Moon Phases animated GIF created by Antonio Cidadao Barbara Gage PSC 1210 Prince George’s Community College.](https://reader035.fdocuments.in/reader035/viewer/2022062300/56649dbc5503460f94aae219/html5/thumbnails/4.jpg)
Moon Phases
o A day and a year on the moon are the same length
o For this reason, the same side of the moon always faces earth
![Page 5: Moon Phases animated GIF created by Antonio Cidadao Barbara Gage PSC 1210 Prince George’s Community College.](https://reader035.fdocuments.in/reader035/viewer/2022062300/56649dbc5503460f94aae219/html5/thumbnails/5.jpg)
Moon Phases
o As the moon revolves around Earth, the relative positions of the moon, Earth, and sun change
o The changing relative positions of the moon, Earth, and sun cause the phases of the moon and eclipses
![Page 6: Moon Phases animated GIF created by Antonio Cidadao Barbara Gage PSC 1210 Prince George’s Community College.](https://reader035.fdocuments.in/reader035/viewer/2022062300/56649dbc5503460f94aae219/html5/thumbnails/6.jpg)
Moon Phases
o The different shapes of the moon you see from Earth are called phases
o In about 29.5 days, the cycle is completed
![Page 7: Moon Phases animated GIF created by Antonio Cidadao Barbara Gage PSC 1210 Prince George’s Community College.](https://reader035.fdocuments.in/reader035/viewer/2022062300/56649dbc5503460f94aae219/html5/thumbnails/7.jpg)
Moon Phaseso The phase of the moon you
see depends on how much the sunlit side of the moon faces earth
![Page 8: Moon Phases animated GIF created by Antonio Cidadao Barbara Gage PSC 1210 Prince George’s Community College.](https://reader035.fdocuments.in/reader035/viewer/2022062300/56649dbc5503460f94aae219/html5/thumbnails/8.jpg)
1) New Moon
o The sunlit side faces away from the Earth
![Page 9: Moon Phases animated GIF created by Antonio Cidadao Barbara Gage PSC 1210 Prince George’s Community College.](https://reader035.fdocuments.in/reader035/viewer/2022062300/56649dbc5503460f94aae219/html5/thumbnails/9.jpg)
2) Waxing Crescento The portion of the moon you
can see is waxing, or growing, into a crescent shape.

3) First Quarter
o You can see half of the sunlit side of the
moon.

4) Waxing Gibbouso The moon
continues to wax. The visible shape of the moon is called gibbous.
![Page 12: Moon Phases animated GIF created by Antonio Cidadao Barbara Gage PSC 1210 Prince George’s Community College.](https://reader035.fdocuments.in/reader035/viewer/2022062300/56649dbc5503460f94aae219/html5/thumbnails/12.jpg)
5) Full Moono The
entire sunlit side faces the Earth.

6) Waning Gibbous
o The portion of the moon you can see wanes, or shrinks.
![Page 14: Moon Phases animated GIF created by Antonio Cidadao Barbara Gage PSC 1210 Prince George’s Community College.](https://reader035.fdocuments.in/reader035/viewer/2022062300/56649dbc5503460f94aae219/html5/thumbnails/14.jpg)
7) Third Quarter
o You can see half of the moon’s lighted side
![Page 15: Moon Phases animated GIF created by Antonio Cidadao Barbara Gage PSC 1210 Prince George’s Community College.](https://reader035.fdocuments.in/reader035/viewer/2022062300/56649dbc5503460f94aae219/html5/thumbnails/15.jpg)

How do you know if it is a Waning or Waxing phase?

Eclipses
![Page 19: Moon Phases animated GIF created by Antonio Cidadao Barbara Gage PSC 1210 Prince George’s Community College.](https://reader035.fdocuments.in/reader035/viewer/2022062300/56649dbc5503460f94aae219/html5/thumbnails/19.jpg)
Intro to Eclipseso When the Sun or Moon is blocked
from the Earth an eclipse occurs.o When the sun is blocked, it is
called a solar eclipseo When the moon is blocked, it is
called a lunar eclipse
![Page 20: Moon Phases animated GIF created by Antonio Cidadao Barbara Gage PSC 1210 Prince George’s Community College.](https://reader035.fdocuments.in/reader035/viewer/2022062300/56649dbc5503460f94aae219/html5/thumbnails/20.jpg)
Solar Eclipseo The moon (in new
moon phase) passes directly between the earth and the sun blocking the sunlight
o Remember “SME”The shadow of the Moon falling on the Earth. Anyone under the shadow will
see the solar eclipse.
![Page 21: Moon Phases animated GIF created by Antonio Cidadao Barbara Gage PSC 1210 Prince George’s Community College.](https://reader035.fdocuments.in/reader035/viewer/2022062300/56649dbc5503460f94aae219/html5/thumbnails/21.jpg)

o People within the umbra (or dark shadow region) see the total eclipse
o People within the penumbra (or lighter shadow region) see only a partial eclipse
o It is not safe to look directly at a solar eclipse (you need special glasses)
![Page 23: Moon Phases animated GIF created by Antonio Cidadao Barbara Gage PSC 1210 Prince George’s Community College.](https://reader035.fdocuments.in/reader035/viewer/2022062300/56649dbc5503460f94aae219/html5/thumbnails/23.jpg)
o In a total solar eclipse, the outer layer of the sun’s atmosphere, the solar corona, is visible surrounding the dark disk of the moon
o The sky grows dark as night, and an eerie color and you can see the stars
![Page 24: Moon Phases animated GIF created by Antonio Cidadao Barbara Gage PSC 1210 Prince George’s Community College.](https://reader035.fdocuments.in/reader035/viewer/2022062300/56649dbc5503460f94aae219/html5/thumbnails/24.jpg)
Lunar Eclipseo The Earth passes directly between
the Moon and the Sun (during the Full Moon phase)
o Remember “SEM” o Earth casts a shadow on the Moono Everyone on Earth (at night) will
see the Lunar Eclipse
![Page 25: Moon Phases animated GIF created by Antonio Cidadao Barbara Gage PSC 1210 Prince George’s Community College.](https://reader035.fdocuments.in/reader035/viewer/2022062300/56649dbc5503460f94aae219/html5/thumbnails/25.jpg)

Lunar EclipseoWhen the moon is in the Earth’s umbra, you see a total lunar eclipseoWhen the moon is not totally in the Earth’s umbra, you see a partial lunar eclipse
![Page 27: Moon Phases animated GIF created by Antonio Cidadao Barbara Gage PSC 1210 Prince George’s Community College.](https://reader035.fdocuments.in/reader035/viewer/2022062300/56649dbc5503460f94aae219/html5/thumbnails/27.jpg)
Lunar Eclipseo During a total lunar eclipse, the moon obtains a reddish tint (also called blood moon) because the Earth’s atmosphere bends the red part of the visible sun light toward the moono You do not need special glasses to see a lunar eclipse
![Page 28: Moon Phases animated GIF created by Antonio Cidadao Barbara Gage PSC 1210 Prince George’s Community College.](https://reader035.fdocuments.in/reader035/viewer/2022062300/56649dbc5503460f94aae219/html5/thumbnails/28.jpg)
Question?
Shouldn’t there be a lunar eclipse every time we have a full moon? (Once per month)
![Page 29: Moon Phases animated GIF created by Antonio Cidadao Barbara Gage PSC 1210 Prince George’s Community College.](https://reader035.fdocuments.in/reader035/viewer/2022062300/56649dbc5503460f94aae219/html5/thumbnails/29.jpg)
The Earth revolves around the Sun on a flat plane.
The Moon revolves around Earth on a tilted plane. This means that when the moon is full, it may be above or below the shadow of the Earth and no eclipse will occur. Two times a year, the sun, earth, and moon will align, causing an eclipse.

o The Earth moves through space in 2 major ways: rotation and revolution
o Rotation is the spinning of the Earth on its axiso It takes Earth about 24 hours to rotate once. This
24 hour cycle of day and night is called a day
![Page 31: Moon Phases animated GIF created by Antonio Cidadao Barbara Gage PSC 1210 Prince George’s Community College.](https://reader035.fdocuments.in/reader035/viewer/2022062300/56649dbc5503460f94aae219/html5/thumbnails/31.jpg)
Day and Nighto An Earth’s rotation causes day and nighto It is day on the side of the Earth facing the
sun. o It is night on the side of the Earth facing
away from the sun.

Yearo Revolution is the movement of one object around
anothero The earth travels around the sun in one year
(365.24 days) o The earth’s path or orbit around the sun is not
circular (it is an ellipse or elongated circle)
