Transcript of Copy of Moon Phases and Eclipses

Solar Eclipses
-Often associated with bad omens
- The moon passes between the sun and earth & fully/partially blocks the sun
Phase 7: Third Quarter
Moon Phases and Eclipses
Introduction to the Moon
- The surface of the moon has a pattern (phases)
- there are 8 phases:

1. new moon
2. waxing crescent
3. first quarter
4. waxing gibbous

Phase 1: New Moon
- Occurs when moon is between the earth and sun
- Illuminated side faces the sun
Phase 2: Waxing Crescent
- moon isn't positioned between sun and earth anymore
- Is seen in the west after sunset
- Also called half moon
- left half illuminated and right half in its shadows

Phase 4: Waxing Gibbous
- Rises between noon & sunset
Phase 6:Waning Gibbous
- moon is moving closer to the sun
- The illuminated side is turning away from Earth
By: Christine Cheung & Felicia Nip
- Waning is seen in the east before dawn
- Moves eastward around Earth (in orbit motion)
Eclipses
Phase 8: Waning Crescent
- A darkening of a celestial object due to the position of another celestial object
Two main types of eclipses: solar & lunar
Phase 3:First Quarter
- Also called half moon


Parts of an Eclipse
-3 parts of an eclipse:
-Umbra
-Penumbra
-Antumbra

Umbra: darkest part of a shadow that is cast by either the sun, earth or any other objects during an eclipse
Phase 5: Full Moon
Penumbra: partially shaded outer region by the sun, earth, or any other objects
- Opposite of the new moon
Antumbra: the part of the shadow that's casted by the light from the sun
Lunar Eclipses
-Occurs when the earth is positioned between the Sun and Moon
- Illuminated side of the moon starts to deplete or get darker.
THANK YOU :)
- Makes the moon look orange/red
- Three types: total, partial & penumbral lunar eclipses
- It's RARE & can only be seen during new moon
Fun Facts
- When we are on Earth, we always see the exact same side while the other one is in the shadows
- The moon rotates at 10 miles per hour
-can only see the shadow of the moon
- First quarter rises at noon, and sets near midnight.
-Comes a week after new moon
- Shows half illuminated and half in shadows
-Easier to see than a waxing crescent
-Most of the illuminated side faces Earth
-Entire illuminated side faces Earth

- Can be seen about 2 weeks into the cycle
5. full moon
6. waning gibbous
7. third quarter
8. waning crescent
Moon phases start over after this phase.
Use this saying to help you remember the difference between Waning and Waxing

"Wax on, Wipe off"

Waning - Light on left, moon is getting less
Waxing - Light on right, moon is getting bright
"Waxing" is when the moon is getting brighter
"Waning" means the illuminated part we see is getting less (moon is getting darker)
