Which outcome increases when a desert dune field’s vegetation cover falls?

💡 Explanation

Amplified saltation happens because removal of vegetation increases wind speed at the surface, accelerating impact and sand creep. This raises the sand flux by saltation exponentially rather than reducing bedrock abrasion, which involves different grain sizes. The other options are independent.
