Which mechanism enlarges fjords when sea level rises postglacially?

💡 Explanation

Enlargement of fjords by tidal scour occurs because the increased connection to the open ocean intensifies wave action and tidal currents, causing enhanced erosion of the fjord walls; therefore, wave erosion enlarges the fjord, rather than ice wedging or dissolution.
