Which of the following generally form at the upper part of a river?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. Gorges.
At the upper part of a river, the most common landforms are gorges. This part of the river is typically steep and flows rapidly downhill, causing intense vertical erosion. As a result, the river cuts deep into the landscape, forming narrow and steep-sided valleys known as gorges. These are characteristic of the youthful stage of a river.
Other Options:
-
Meanders and oxbow lakes usually form in the middle and lower courses of a river, where the gradient is gentler and lateral erosion dominates.
-
Floodplains are flat, wide areas found in the lower course of a river, formed by the deposition of sediments during floods.
