Let's solve the worksheet step by step.

Q.1: Label the moon phases on the diagram below

We are given a circular diagram showing the Moon’s orbit around Earth, with 8 positions of the Moon at different phases. The phases to label are:

- Waning gibbous
- Full moon
- Waxing gibbous
- New moon
- First quarter
- Waning crescent
- Third quarter
- Waxing crescent

We need to correctly place these labels based on the position of the illuminated part of the Moon as seen from Earth.

#### Understanding Moon Phases:
The Moon goes through phases due to its position relative to the Earth and Sun. As it orbits Earth, we see different portions of the illuminated side.

- New Moon: Moon is between Earth and Sun → we see no light (dark side facing us).
- Waxing Crescent: Small sliver visible, growing.
- First Quarter: Half illuminated (right side in Northern Hemisphere).
- Waxing Gibbous: More than half lit, increasing.
- Full Moon: Entire face illuminated (opposite Sun).
- Waning Gibbous: Decreasing, more than half lit.
- Third Quarter: Half lit, left side illuminated.
- Waning Crescent: Small sliver, decreasing.

Note: The direction of the Moon’s orbit is counterclockwise (as shown by arrows). We start from the New Moon, then move through waxing phases, full moon, waning phases.

Let’s go around the diagram clockwise starting from the top (since the arrows show counterclockwise motion):

1. Top position → New Moon
- The Moon is directly between Earth and Sun → dark side faces Earth.

2. Top-right → Waxing Crescent
- A small sliver on the right is illuminated; growing.

3. Bottom-right → First Quarter
- Right half is lit.

4. Bottom → Waxing Gibbous
- More than half lit, still growing.

5. Bottom-left → Full Moon
- Entire face illuminated.

6. Left → Waning Gibbous
- More than half lit but decreasing.

7. Top-left → Third Quarter
- Left half illuminated.

8. Top-center → Waning Crescent
- Small sliver on the left, decreasing.

Wait — actually, let's trace the arrows carefully.

The arrows point counterclockwise, so the sequence is:

Start at the top (between Earth and Sun) → that’s New Moon.

Then moving counterclockwise:

1. Top → New Moon
2. Top-right → Waxing Crescent
3. Right → First Quarter
4. Bottom-right → Waxing Gibbous
5. Bottom → Full Moon
6. Bottom-left → Waning Gibbous
7. Left → Third Quarter
8. Top-left → Waning Crescent

Now, match the labels to the blank boxes.

Assuming the blanks are in this order (going clockwise or following the diagram):

Let’s number the blanks:

- Top: ___________ → New Moon
- Top-right: ___________ → Waxing Crescent
- Right: ___________ → First Quarter
- Bottom-right: ___________ → Waxing Gibbous
- Bottom: ___________ → Full Moon
- Bottom-left: ___________ → Waning Gibbous
- Left: ___________ → Third Quarter
- Top-left: ___________ → Waning Crescent

So, fill in the blanks accordingly:

> Top: New moon
> Top-right: Waxing crescent
> Right: First quarter
> Bottom-right: Waxing gibbous
> Bottom: Full moon
> Bottom-left: Waning gibbous
> Left: Third quarter
> Top-left: Waning crescent

✔ This matches the correct phase order.

Q.2: True or False

#### 1. The moon makes one complete revolution around the Earth every year.
✘ False
- The Moon revolves around Earth approximately every 27.3 days (sidereal month), not once per year.
→ F

#### 2. Moon revolves around Earth, Earth revolves around Sun.
✔ True
- Yes, the Moon orbits Earth, and Earth orbits the Sun.
→ T

#### 3. There are six phases of the moon.
✘ False
- There are eight main phases: New Moon, Waxing Crescent, First Quarter, Waxing Gibbous, Full Moon, Waning Gibbous, Third Quarter, Waning Crescent.
→ F

#### 4. The moon does not produce its own light.
✔ True
- The Moon reflects sunlight. It does not generate its own light.
→ T
