Worksheet explaining the phases of the moon with a diagram and educational content.

It looks like you've uploaded a worksheet titled "Earth-Sun-Moon System: Phases of the Moon", which is designed to teach students about the lunar phases and how they are caused by the relative positions of the Earth, Sun, and Moon.

However, the bottom portion of the worksheet (where the questions are located) appears blurred or obscured, so I can't read the specific questions or answer them directly. But based on the visible content, I can help you understand how to solve this type of problem and explain the concepts involved, so you can complete the worksheet on your own.

🔍 Understanding the Diagram

The circular diagram shows the Moon’s orbit around Earth, with eight key positions. The Sun is off to the right, shining light from that direction (indicated by arrows labeled "Sunlight").

- The blue circle in the center represents Earth.
- The smaller circles around it represent the Moon at different points in its orbit.
- Each Moon has a yellow (lit) side and a dark side, showing which part is illuminated by the Sun.
- You're supposed to imagine yourself standing on Earth, looking up at the Moon from the base of the dotted line (which points toward the Moon).

🌕 How to Identify Moon Phases

As the Moon orbits Earth, we see different portions of its sunlit side. The phase depends on:

1. Which side of the Moon is lit by the Sun
2. Which side of the Moon is facing Earth

Here’s a guide to match each position in the diagram to the correct phase:

| Position | Phase Name | Description |
|--------|--------------------|-----------|
| 1 | New Moon | Moon between Earth and Sun; dark side faces Earth → not visible |
| 2 | Waxing Crescent | Small sliver on the right side lit (growing) |
| 3 | First Quarter | Right half lit (like a "D") |
| 4 | Waxing Gibbous | More than half lit, right side brighter |
| 5 | Full Moon | Entire face lit (opposite Sun) |
| 6 | Waning Gibbous | More than half lit, left side brighter |
| 7 | Last Quarter | Left half lit (like a "C") |
| 8 | Waning Crescent | Small sliver on the left side lit (shrinking) |

> ⚠️ Note: “Waxing” means growing; “Waning” means shrinking. In the Northern Hemisphere:
> - Waxing = lit part on the right
> - Waning = lit part on the left

✔ How to Answer the Questions

Even though the actual questions are blurry, here are common types of questions on this worksheet and how to answer them:

#### 🔹 Question Type 1: Match the position to the moon phase
Example:
*What phase is the Moon in when it's at position 3?*

👉 Look at the diagram:
- Position 3: The Moon is lit on the right half → First Quarter

✔ Answer: First Quarter

---

#### 🔹 Question Type 2: Draw or label the phase seen from Earth
Example:
*Draw what the Moon would look like from Earth at position 6.*

👉 At position 6:
- The Moon is mostly lit but the left side is lit.
- This is Waning Gibbous

✔ Sketch a circle with most of the left side shaded yellow (lit), and the right side dark.

---

#### 🔹 Question Type 3: Order the phases
Example:
*List the phases in order as the Moon moves from New Moon to Full Moon.*

✔ Answer:
New Moon → Waxing Crescent → First Quarter → Waxing Gibbous → Full Moon

---

#### 🔹 Question Type 4: Explain why the Moon changes shape
Answer:
The Moon does not produce its own light. It reflects sunlight. As the Moon orbits Earth, the angle between the Sun, Moon, and Earth changes, so we see different portions of the sunlit side. This causes the apparent shape (phase) to change.

🌐 Important Notes

- The model assumes Northern Hemisphere perspective.
- From the Southern Hemisphere, the Moon appears flipped — crescents appear on the opposite side.
- The cycle takes about 29.5 days (a lunar month).
- The Moon always keeps the same side facing Earth due to tidal locking.

💡 Tips for Completing Your Worksheet

1. Use the top diagram to determine the phase at each orbital position.
2. Look at the lit side of the Moon in the diagram.
3. Compare it to the labeled phases below (New Moon, Waxing Crescent, etc.).
4. Match the orientation: lit side on the right = waxing; lit side on the left = waning.
5. Fill in the blanks accordingly.
