Which landform results when differential erosion breaches arches in coastal headlands?

💡 Explanation

Sea stacks emerge because differential erosion selectively removes weaker rock, creating arches which then collapse; therefore, isolated stacks remain, rather than a tombolo which involves sediment deposition or sandspits formed by longshore drift.

• Which mechanism reduces soil fertility when prolonged floodplain inundation occurs on alluvial plains used for agriculture?
• Near coral reef islands, which process maintains channel depths?
• Which feedback occurs because thermokarst development destabilizes Arctic slopes?
• Which outcome is accelerated when increased sediment deposition obstructs subduction zones?
• Which outcome is triggered when differential stress exceeds limit?
• Which outcome commonly results when river downcutting slows and lateral erosion continues within a meander bend?
