The lack of precipitation causes the brand new accumulation from sand, while the water is an important cause of the procedure of erosion and transportation from sediments. Particular plant life will get small gaps or cracks regarding the stones where they can develop and obtain nutrition.

Consequently, breeze and you will water erode the mineral-rich topsoil. Overgrazing and deforestation lose flowers one to point the newest soil. Such items is overgrazing of animals, deforestation, overcultivation out of farmland and you will worst irrigation techniques.
