15. How does this lead to desert? Vegetation roots bind the soil. Vegetation dies. Soil is left exposed. Sun bakes the soil and it cracks. Wind will blow away the soil. Leaves are no longer present to intercept rain. The soil is washed away. The soil is degraded, over time losing fertility and structure.
