Which outcome results when a meander erodes through its neck during enhanced streamflow?

💡 Explanation

An oxbow lake forms due to stream meander cutoff, where increased erosion during flooding leads to a channel breaching across the meander neck via avulsion; therefore, a separate water body forms, rather than an increase in sinuosity requiring more gradual processes.

• Which erosional process forms a finger lake basin within a glacially carved valley?
• Which depositional pattern develops when a mountain stream abruptly enters a broad, dry valley?
• Which displacement results from intensifying the Coriolis effect on prevailing winds encountering a mountain range?
• Which atmospheric outcome significantly reduces convective precipitation when persistent high pressure systems induce the subsidence effect?
• Which land deformation results when thawing permafrost causes widespread ground subsidence?
