Question

What are meanders?
A) Zigzag flow of river
B) Circular flow of river
C) Straight flow of river
D) None of these

Answer 1

Hint: A river is a naturally flowing, usually freshwater watercourse that flows towards an ocean, sea, lake, or another river. A river may flow into the ground and become dry at the end of its course before reaching another source of water in some instances.

Complete answer:
The correct option is a meandering curve or bend in a river is referred to as a "meander." In the middle and lower reaches of a river, meanders are common landforms. Meander gradients are often gentler, and they are subject to lateral (sideways) erosion, which widens the river channel in the middle and lower courses.

In the channel of a river, stream, or other watercourse, a meander is a succession of regular sinuous curves, bends, loops, turns, or windings. It's also a way of saying that you're walking slowly.

It's created when a stream or river runs across its floodplain or adjusts its channel within a valley, swinging from side to side.

A meander is formed when a stream or river erodes the sediments that make up an outer, concave bank (cut bank) and deposits them, together with other debris, downstream on an inner, convex bank, which is usually a point bar.

Meanders are Circular flow of the river. Therefore the correct answer is option ‘B’.

Note: Rivers, of course, always flow downwards! When water flows downhill from one location to another, it forms a stream or a river. As a result, most rivers start high in the mountains, when winter snow or ancient glaciers are melting.
