← GeographyWhich event triggers landscape evolution of oxbow lake's infill?
A)Vegetation induced sedimentation✓
B)Glacial isostatic rebound
C)Subduction zone earthquake
D)Thermohaline overturning collapse
💡 Explanation
When plants colonize an oxbow lake because decreased flow velocity induces organic and inorganic sediment trapping and accumulation, accelerating the lake's terrestrialization via paludal system formation. Therefore sedimentation develops from infill, rather than rebound, quake, or heat overturning collapses, driven by geologic processes respectively across large geographic areas.
