Lunar Cycle Vocabulary

5. Maria Dark level regions. Latin for “sea”
Formed from lava flows/meteoroid impacts.

6. Highlands Light/elevated regions or mountains.
Formed from crater impacts ejecting material.

7. Crater
Circular hollow pits.
Formed from meteoroid strikes

8. Regolith
Loose moon rock/dust.

9. Eclipse
When light from a celestial body is blocked by another celestial body.
Solar Eclipse
Lunar Eclipse

10. Tides
the alternate rising and falling of the sea, usually twice in each day at a particular place, due to the attraction (gravitational pull) of the moon and sun.

11. Theory of Moons Origin:
Giant Impact Theory – a planet sized object collided with Earth, and the material formed our moon.

12. New Moon
Side of the moon we see is completely dark. Moon is BETWEEN the sun and the Earth.

13. Lunar Cycle
The appearance of the moon as it makes one full revolution of the Earth. About 28 days.

14. Waxing
Increasing of visible amount of the moon’s illuminated surface. RIGHT side is lit.
From new moon to full moon.
“Waxing is maxing”

15. Waning
The decreasing of the visible amount of the moon’s illuminated surface. LEFT side is lit.
From full moon to new moon.
“Waning is draining”

16. Crescent
Moon is only illuminated in a small sliver.

17. Gibbous
When more than half of the moon is illuminated but not quite full.

18. Full Moon
Side of the moon we see is fully illuminated. Earth is BETWEEN the sun and the moon.

19. 1st Quarter
When half of the moon is lit on the RIGHT side.

20. 3rd Quarter AKA Last Quarter
When half of the moon is lit on the LEFT side.

21. Lunar Cycle Flipbook
Moon Phases

25. Spring and Neap Tides foldable

26. What causes the oceans tides?
The gravitational pull of the moon and the sun (BUT mostly the moon because it is closer to the Earth!)

27. Describe a spring tide and a neap tide
Spring tide occurs during the new and full moon. (Very HIGH high tides and very LOW low tides) THINK STRAIGHT LINE

28. Describe a spring tide and a neap tide
Neap Tides occur during the 1st and 3rd quarter moons. THINK NINETY DEGREE ANGLE

29. What two moon phases occur during the spring tide?
New or Full moon

30. What two moon phases occur during the neap tide?
1st Quarter or 3rd Quarter Moon

31. foldable
ECLIPSES

33. Partial Solar Eclipse
Occurs when the moon covers only a portion of the sun.

34. Total Solar Eclipse Occurs when the moon covers entire sun. Very rare
Total eclipse can last 7 ½ minutes
The corona is visible.
NEW MOON

35. Penumbral Lunar Eclipse
Occurs when moon passes in the penumbra of Earth’s Shadow.
Penumbra is the area of partial shadow.
Moon looks darker

36. Partial Lunar Eclipse
When only part of the moon passes in Earth’s umbra.
UMBRA – total area of shadow.

37. Total Lunar Eclipse
Occurs when the moon passes inside the umbra of Earth’s shadow.
Atmosphere of Earth bends the light from the Sun and filters out all the colors. Only red light passes behind Earth and hits the moon.
FULL MOON
