Which mechanism causes the transformation of an oxbow lake into a marsh environment over time?

💡 Explanation

When agricultural runoff enters oxbow lakes, eutrophication occurs because nutrients increase algae growth, leading to oxygen depletion and increased sedimentation, resulting in shallower water suitable for marsh vegetation. Therefore a marsh transition, rather than rebound, fracturing, or seismic effects which involves unrelated geological mechanisms.

• Which consequence results when magma's slow cooling rate within dikes creates a high viscosity lava that obstructs its own pathway?
• Which outcome is accelerated on slopes with high permafrost content when experiencing thawing?
• Which process limits the height of natural levees formed along a meandering river?
• Which outcome develops when rainfall accelerates the weathering of carbonate bedrock?
• Which outcome occurs when stress exceeds granite's frictional limit along a transform fault?
• Which effect promotes plankton blooms when coastal upwelling transports deep water towards the surface?
