Which outcome occurs when a meandering stream erodes laterally until encountering a resistant geological formation beneath an oxbow?

A)Stream piracy and drainage divide shift✓

B)Increased fluvial terrace formation downstream

C)Accelerated delta formation at river's mouth

D)Enhanced groundwater recharge rates locally

💡 Explanation

Stream piracy happens because differential erosion exposes the bend causing the stream's flow path to divert to a steeper channel thereby forming a new shorter route and 'capturing' the stream. Therefore, it results in stream piracy rather than terraces which depends on sediment load.
