Answer key for "Phases of the Moon" worksheet, illustrating all lunar phases with correct labels.

It looks like you've uploaded an answer key for a worksheet titled *"Phases of the Moon"*. The task is to identify the correct phase of the Moon based on visual representations.

Let me go through each image and explain the correct identification and why it's accurate, using basic lunar phase knowledge:

🔹 Understanding Moon Phases:

The Moon goes through eight main phases in its cycle:
1. New Moon – Not visible (Sun and Moon aligned)
2. Waxing Crescent – Small lit sliver on the right side (growing)
3. First Quarter – Right half lit
4. Waxing Gibbous – More than half lit, right side
5. Full Moon – Entirely lit
6. Waning Gibbous – More than half lit, left side
7. Last Quarter – Left half lit
8. Waning Crescent – Small lit sliver on the left side (shrinking)

> "Waxing" = growing (from new to full)
> "Waning" = shrinking (from full to new)
> Right side lit = waxing, Left side lit = waning

✔ Let's Analyze Each Image:

#### Row 1:
1. Image: Left side lit, small sliver → Waning Crescent
✔️ Correct. A thin crescent on the left means it’s shrinking after full moon.

2. Image: Right side lit, small sliver → Waxing Crescent
✔️ Correct. Growing from new moon; lit part on the right.

3. Image: Fully dark → New Moon
✔️ Correct. No visible illumination.

#### Row 2:
4. Image: Most of the right side lit → Waxing Gibbous
✔️ Correct. More than half lit, growing toward full moon.

5. Image: Fully lit → Full Moon
✔️ Correct. Entire disk illuminated.

6. Image: Right half lit → First Quarter
✔️ Correct. Half lit on the right side; halfway from new to full.

---

#### Row 3:
7. Image: Left side mostly lit → Waning Gibbous
✔️ Correct. More than half lit but decreasing; lit on the left.

8. Image: Right side lit, small sliver → Waxing Crescent
✘ Wait — this one is incorrectly labeled.

- This image shows a small lit portion on the right, which should be waxing crescent.
- But look closely: the label says "waxing crescent", and the image matches that.

✔ Actually, this is correct. It's a waxing crescent (right side lit, growing).

9. Image: Left half lit → Last Quarter
✔️ Correct. Half lit on the left; halfway from full to new.

🛠️ Final Check:

All labels match their corresponding images correctly.

| Image | Phase | Reason |
|------|-------|--------|
| 1 | Waning Crescent | Lit on left, small sliver |
| 2 | Waxing Crescent | Lit on right, small sliver |
| 3 | New Moon | Fully dark |
| 4 | Waxing Gibbous | Right side mostly lit, growing |
| 5 | Full Moon | Fully lit |
| 6 | First Quarter | Right half lit |
| 7 | Waning Gibbous | Left side mostly lit, shrinking |
| 8 | Waxing Crescent | Right side lit, small sliver |
| 9 | Last Quarter | Left half lit |

✔ Conclusion:

This answer key is completely correct! All nine moon phases are accurately identified with proper terminology.

If this were a student worksheet, they would use this answer key to check their work. For learning purposes, students should understand:
- Side of illumination determines if it's waxing (right) or waning (left).
- Amount of light tells whether it's crescent, quarter, gibbous, or full.
