This worksheet helps students identify the three stages of a river and label key features like the source, mouth, and meanders.

Let's solve this step-by-step based on the image and the instructions provided.

Part 1: Fill in the blanks with UC (Upper Course), MC (Middle Course), or LC (Lower Course)

We are given 9 statements about river stages. Let’s analyze each one:

1. "This is the beginning of a river"
→ The upper course is where the river starts.
✔ UC

2. "It starts at the source of a river and continues until the river meets flatter land"
→ This describes the upper course, which begins at the source and ends when the terrain becomes flatter.
✔ UC

3. "The river empties into the sea or lake"
→ This happens at the mouth, which is in the lower course.
✔ LC

4. "The water flows quickly and the river is smaller"
→ Fast-flowing, narrow rivers are typical of the upper course.
✔ UC

5. "The river gets bigger and wider"
→ As the river moves downstream, it gains tributaries and spreads out — this happens in the middle to lower course, but most notably in the middle course as it transitions.
✔ MC

6. "The mouth of the river is found here"
→ The mouth is at the end of the river, in the lower course.
✔ LC

7. "The river begins to slow down"
→ This occurs as the gradient decreases, usually starting in the middle course.
✔ MC

8. "This is the last stage of a river"
→ The lower course is the final stage before the river reaches the sea/lake.
✔ LC

9. "The river becomes even wider and the water flows more slowly"
→ This is characteristic of the lower course, where the river meanders and spreads out.
✔ LC

Part 2: Label the diagram with the correct parts of the river

We are given these terms to use:
- Upper course
- Middle course
- Lower course
- Meander
- Confluence
- Tributary
- Source
- Waterfall
- Mouth

Now let’s label the diagram based on standard river features:

#### Diagram Labels:

- Top left mountain area:
→ Where the river starts → Source

- Area with steep drop (water falling):
→ Waterfall (common in upper course)

- Label 1 (just after source):
→ This is the Upper course

- Label 2 (where river widens and curves):
→ This is the Middle course

- Label 3 (near the end, wide and winding):
→ This is the Lower course

- Curved part of the river in lower section:
→ Meander (a bend in the river)

- Where two rivers join:
→ Confluence (where a tributary joins the main river)

- Smaller stream joining the main river:
→ Tributary

- Where river ends in the sea/lake:
→ Mouth

✔ Final Diagram Labels:

| Position | Label |
|--------|-------|
| Top of mountain (left) | Source |
| Waterfall (arrow pointing to fall) | Waterfall |
| Label 1 | Upper course |
| Label 2 | Middle course |
| Label 3 | Lower course |
| Curved river in lower part | Meander |
| Point where two rivers meet | Confluence |
| Smaller stream joining main river | Tributary |
| End of river in blue body of water | Mouth |

- 1: Upper course
- 2: Middle course
- 3: Lower course
- Meander (curved section)

✔ This completes the worksheet! The river journey starts at the source in the upper course, flows through the middle course where it slows and widens, and ends in the lower course with meanders, tributaries, and finally the mouth.
