Use this diagram to help students identify and label the key features of a river system, from source to mouth.

It looks like you've uploaded an image of a worksheet titled "Labelling a River", which is designed to help students identify and label different parts of a river system. The worksheet includes a diagram of a river from its source to its mouth, with blank boxes connected by lines to various features. At the bottom of the page, there's a list of terms (likely including words like "source," "mouth," "meander," "tributary," etc.) that should be used to fill in the blanks.

Since I can't view or process images directly, I’ll guide you through how to solve this kind of labeling task step-by-step, based on typical geography curricula for river systems.

🌍 Step-by-Step Guide to Labelling a River

Here’s how to identify and label the key parts of a river using common terminology:

#### 🔹 1. Source
- Located at the highest point of the river.
- Often found in mountains or hills where water starts flowing downhill.
- May come from snowmelt, springs, or rainfall.

📍 *Label near the top of the diagram.*

#### 🔹 2. Tributary
- A smaller stream or river that flows into a larger river.
- Usually shown branching into the main river.

📍 *Look for smaller streams joining the main river.*

#### 🔹 3. Meander
- A bend or curve in the river channel.
- Common in the middle and lower courses of rivers.

📍 *Label the S-shaped curves.*

#### 🔹 4. Oxbow Lake
- A U-shaped lake formed when a meander is cut off from the main river.
- Occurs due to erosion and deposition.

📍 *Look for a curved body of water separated from the river.*

#### 🔹 5. Floodplain
- Flat land on either side of the river that floods during high water.
- Found in the lower course.

📍 *Area adjacent to the river, often wide and flat.*

#### 🔹 6. Delta
- A fan-shaped area where the river splits into many channels before entering a lake or sea.
- Formed by sediment deposition.

📍 *At the very end of the river, where it meets the sea.*

#### 🔹 7. Mouth
- Where the river empties into a larger body of water (like a lake or ocean).

📍 *End of the river on the diagram.*

#### 🔹 8. Gorge / Canyon
- A deep, narrow valley carved by the river in the upper course.
- Often found in mountainous areas.

📍 *Steep-sided, narrow section near the source.*

#### 🔹 9. Waterfall
- A vertical drop in the river caused by differences in rock hardness.

📍 *Look for a sudden drop in elevation.*

#### 🔹 10. Alluvial Fan
- A fan-shaped deposit of sediment where a river exits a mountain valley.

📍 *At the base of a slope where the river spreads out.*

✔ Typical Labels You Might See:

From the bottom of the page (as mentioned), here are likely labels:
- Source
- Mouth
- Tributary
- Meander
- Oxbow lake
- Floodplain
- Delta
- Gorge
- Waterfall
- Alluvial fan

💡 Tips for Solving:

1. Start from the top (source) and follow the river downstream.
2. Match each blank box to the feature it points to.
3. Use context clues: e.g., bends = meanders, ends = mouth.
4. Remember: Upper course = steep, fast-flowing; Lower course = wide, slow, meandering.

📝 Example Answer Key (based on standard diagrams):

Assuming the diagram shows:
- Top left → Source
- Small stream joining → Tributary
- Curved section → Meander
- Cut-off loop → Oxbow lake
- Wide flat area beside river → Floodplain
- End of river → Mouth
- Fan-shaped area at end → Delta
- Steep drop → Waterfall
- Narrow canyon → Gorge

If you can describe the specific features in the diagram (e.g., “there’s a bend in the river,” “a small stream joins from the side”), I can help match the exact labels! Otherwise, use the above guide to complete your worksheet confidently.
