Which outcome occurs more rapidly when sandstone bedrock undergoes increased hydraulic action?

💡 Explanation

Cliff base undercutting increases with greater hydraulic pressure because the increased force behind hydraulic action weakens the joints and bedding surfaces eroding the base rather than allowing sediment compaction or offshore deposit; therefore, there's increased cave creation near the waterline rather than accretion above it.
