Which risk dramatically increases when arctic slope gradients exceed 5 degrees?

💡 Explanation

Accelerated soil creep occurs because the increased slope steepness amplifies the effect of solifluction in permafrost regions; therefore, soil displacement is greatly increased, rather than processes directly linked to thermokarst lakes or other distinct mechanisms.
