Which outcome occurs when glaciers retreat in semi-arid regions?

💡 Explanation

Loess deposits increase because glacial retreat exposes large quantities of fine silt. This material, transported by katabatic winds through the mechanism of aeolian transport, is capable of forming thick loess blankets. Therefore extensive deposition happens rather than localized geologic activity.
