The process of head ward erosion will lead to the formation of
Answer Details
Let's understand the term **headward erosion**. **Headward erosion** refers to the process where a river or stream erodes its source region, causing the stream's origin to move backward away from the direction of water flow. This process can have several impacts and can lead to the formation of certain landforms.
Among the options provided, **headward erosion** is most commonly associated with the formation of **river capture**. When **headward erosion** continues over time, it can cause one river to extend its course and intersect with a neighboring river, capturing its flow. This event is known as **river capture** or **stream piracy**. Essentially, the rapid erosion at the river's source enables it to cut through the drainage divide and capture the headwaters of another river.
Let's briefly see why the other options are less relevant to **headward erosion**:
**Potholes** are typically formed on the riverbed as a result of mechanical weathering and the swirling movement of water and debris, rather than headward erosion.
**Oxbow lakes** form when a meander from a river is cut off, creating a free-standing body of water, which is more a result of lateral erosion rather than headward erosion.
**Alluvial cones** or **alluvial fans** form where a river or stream spreads out sediment as it exits a mountainous area onto a flatter plain. This is not directly caused by **headward erosion**, but rather sediment deposition.
Therefore, the process of **headward erosion** most directly leads to the formation of **river capture**.
