Which outcome occurs when persistent wave action erodes cliff foundations?

💡 Explanation

The undercutting action results in the formation of sea caves because differential erosion weakens the rock; therefore causing cave formation, rather than calving or vent formation which involve independent thermal and tectonic conditions entirely.
