Which outcome occurs when groynes impede drift alongshore?

💡 Explanation

Sediment builds on the updrift side because sediment transport is blocked via sediment interruption; therefore, accretion happens updrift rather than balanced deposition wherein sediment would constantly move.

• Which outcome occurs when glacial meltwater deposits sediment?
• Which process primarily drives the formation of a stepped or terraced cirque morphology in mountainous regions?
• Which mechanism determines the rate of sediment subduction along an accretionary wedge?
• Which erosional outcome occurs when a meandering river channel nears a geologic fault line?
• Which mechanism influences stream meandering in the mid-latitudes due to Earth's rotation?
• Which mechanism causes mantle plume volcanism far from subduction zones or plate boundaries?
