Which process consistently rebuilds sand eroded around coastal stacks?

💡 Explanation

Longshore drift transports sediments along coasts; because waves approach at an angle, sediment is moved along the beach and re-deposited therefore forming sandbars that stabilize stacks, rather than isostatic rebound which involves uplift.

• Which risk increases significantly when freeze-thaw cycles accelerate solifluction rates on arctic construction sites?
• Which sediment transport mechanism causes varves to form in glacial lakes during seasonal changes?
• Which mechanism causes braided stream formation across an alluvial plain after rapid glacial retreat?
• Which process amplifies stream incision when tectonic uplift increases base level fall rates significantly?
• Which outcome occurs when floodplains lack riparian vegetation?
• Which outcome results when pre-existing rocks undergo differential erosion by wind?
