Which process limits soil formation within an arid region alluvial fan system?

💡 Explanation

When flash floods occur, erosion removes topsoil faster than it can form, due to the arid climate inhibiting biological activity so that regolith development is slow. Therefore erosion limits the soil formation, rather than deposition, leaching or stabilization each requiring different conditions to dominate.
