A river carrying sediment to an estuary continually shifts its delta morphology; which factor reduces the sediment-driven land formation?

💡 Explanation

Increased sea surface currents cause the longshore drift of sediment away from the delta, lowering the land formation because sediment is transported seaward rather than depositing there; therefore, stronger currents reduce the likelihood of delta progradation rather than increasing sediment delivery.

• Which outcome occurs when rising sea temperatures accelerate glacial melt and coastal erosion, disrupting sediment transport?
• Which hydrogeologic mechanism causes the formation of a kettle lake following glacial retreat where till depression exists?
• Which mechanism creates a stratified water column within a fjord following a glacial meltwater pulse?
• Which process accelerates limestone sinkhole formation below pavement?
• Which mechanism prevents constant seismic activity along a transform fault like the San Andreas?
• Which volcanic ash hazard results when atmospheric moisture increases?
