What natural feature can form from the winding of a meandering river?

• A. Delta
• B. Oxbow lake
• C. Estuary
• D. Wetland

Answer: (B)

When a river meanders, it follows a winding path, creating curves and bends over time. As the river continues to erode the outer bank of these curves and deposit sediment on the inner bank, the bends become more pronounced. Eventually, during periods of high flow or flooding, the river may cut through a narrow neck of land between two bends, creating a new, straighter channel. The abandoned meander loop can then become isolated from the main river flow. Over time, sediment fills in this disconnected loop, forming what is known as an oxbow lake. This process illustrates the dynamic nature of river systems and their capacity for change. Oxbow lakes are characteristic features resulting directly from the erosion and deposition processes associated with meandering rivers, highlighting the interplay between water flow and the landscape. The other options—delta, estuary, and wetland—represent different hydrological features that arise from various processes or settings, but they are not the direct result of meander winding like an oxbow lake is.
