Which risk increases as glacial isostatic rebound elevates fjord landmasses?

💡 Explanation

Increased topography results in steeper slopes exposed to wave action; this triggers increased coastal erosion because unloading promotes uplift and steepening. Therefore, coastal erosion increases, rather than submarine slides being enhanced because of rebound affecting sediment stability less.
