Why is atmospheric dust more associated with desert regions?
Answer and explanation
Correct answer: Because particles are easily lifted by wind from dry loose surfaces
The governing process is wind erosion and the movement of suspended particles. Deserts commonly have dry, loose and sparsely vegetated surfaces, so strong winds can detach and carry fine mineral particles into the atmosphere. Rainfall and plant cover are limited, reducing the binding of soil. Thus option C is correct; high rainfall, glacier melting and falling seawater do not explain desert dust.
