What characterizes a meandering river?

• A. A straight and narrow water flow
• B. A river that curves and winds
• C. A river that flows rapidly
• D. A river with steep banks

Answer: (B)

A meandering river is primarily characterized by its tendency to curve and wind as it flows across the landscape. This sinuous pattern can be attributed to the way in which the river erodes its banks and deposits sediment on the opposite side of bends, leading to a dynamic and continually changing course. As the river flows, the water moves faster on the outside of the bends, causing more erosion in those areas, while slower water on the inside allows for sediment deposition. Over time, this process increases the degree of curvature, resulting in a distinctive meandering appearance. Meandering rivers often create oxbow lakes and other features as they evolve, making them an essential subject of study in hydrology and geomorphology. Understanding the behavior of meandering rivers is crucial for managing ecosystems, flood risks, and sediment transport.
