Which adverse outcome follows the loss of vegetation cover stability on thick loess deposits?

💡 Explanation

Increased desertification occurs when loess deposits lose vegetation; the reduced cohesion weakens the soil's structure and makes it susceptible to wind erosion via deflation. This positive feedback accelerates desert expansion, because topsoil is lost, rather than other topographical or chemical changes.
