Which risk increases when ancient ziggurats experience uneven settling?

💡 Explanation

Accelerated mortar joint salt weathering occurs because differential settlement causes cracks that increase the capillary action of water, which carries salts to the surface where they crystallize and damage the structure; therefore weathering increases, rather than other effects stemming from seismic activity.
