Match each landform term to its correct definition on this educational worksheet.

Task: Landform Matching

The task is to match each landform term on the left with its corresponding definition on the right. Below is the solution with explanations for each match.

---

#### 1. Delta
- Definition: "triangular section of land built up at a river’s mouth"
- Explanation: A delta is a landform that forms when a river deposits sediment (usually sand and mud) as it enters a slower-moving body of water, such as a lake or ocean. This deposition creates a triangular-shaped area at the river's mouth.

---

#### 2. Fjord
- Definition: "long, steep-sided glacial valley now filled by seawater"
- Explanation: A fjord is a narrow inlet of the sea between cliffs or steep slopes, typically formed by glacial erosion. When glaciers retreat, the valley they carved out is often flooded by seawater, creating a fjord.

---

#### 3. Plain
- Definition: "flat or gently rolling lands"
- Explanation: A plain is a large area of flat or gently rolling land. Plains are typically low-lying regions with minimal elevation changes, often found in areas where rivers have deposited sediment over time.

---

#### 4. Dune
- Definition: "windblown sand that has formed hills in deserts and on beaches"
- Explanation: A dune is a mound or ridge of sand that has been shaped by wind. These formations are common in deserts and along coastlines where wind erosion and deposition occur.

---

#### 5. Plateau
- Definition: "flat land mass higher than the surrounding land, with at least one steep side"
- Explanation: A plateau is an elevated land area with a relatively flat top and steep sides. It is higher than the surrounding landscape and often has distinct edges where the elevation drops sharply.

---

#### 6. Cliff
- Definition: "high, steep or overhanging rock face"
- Explanation: A cliff is a steep or vertical face of rock or earth. Cliffs are typically formed by erosion, tectonic activity, or other geological processes that create sharp, high elevations.

---

#### 7. Mesa
- Definition: "flat-topped, elevated land"
- Explanation: A mesa is a flat-topped hill or mountain with steep sides. Mesas are often remnants of larger plateaus that have been eroded over time, leaving behind isolated, elevated flat surfaces.

---

#### 8. Archipelago
- Definition: "a group of closely scattered islands"
- Explanation: An archipelago is a chain or cluster of islands grouped together in a body of water. Examples include the Hawaiian Islands and the Philippines.

---

#### 9. Glacier
- Definition: "large body of ice that moves across the earth’s surface"
- Explanation: A glacier is a massive, slow-moving body of ice that forms from compacted snow over many years. Glaciers move under their own weight and can shape landscapes through erosion and deposition.

---

#### 10. Landform
- Definition: "any natural shape found on Earth’s surface"
- Explanation: A landform is a general term for any natural feature on the Earth's surface, including mountains, valleys, plains, and bodies of water. It encompasses all physical features created by geological processes.

Final Matchings:

1. Delta → "triangular section of land built up at a river’s mouth"
2. Fjord → "long, steep-sided glacial valley now filled by seawater"
3. Plain → "flat or gently rolling lands"
4. Dune → "windblown sand that has formed hills in deserts and on beaches"
5. Plateau → "flat land mass higher than the surrounding land, with at least one steep side"
6. Cliff → "high, steep or overhanging rock face"
7. Mesa → "flat-topped, elevated land"
8. Archipelago → "a group of closely scattered islands"
9. Glacier → "large body of ice that moves across the earth’s surface"
10. Landform → "any natural shape found on Earth’s surface"
