INTRODUCTION
desert, any large, extremely dry area of land with sparse vegetation. It is one of Earth’s major types of ecosystems, supporting a community of distinctive plants and animals specially adapted to the harsh environment.Desert environments are so dry that they support only extremely sparse vegetation; trees are usually absent and, under normal climatic conditions, shrubs or herbaceous plants provide only very incomplete ground cover. Extreme aridity renders some deserts virtually devoid of plants; however, this barrenness is believed to be due in part to the effects of human disturbance, such as heavy grazing of cattle, on an already stressed environment.
OBJECTIVES
3.Explain that deserts originate from a variety of processes and therefore form in a variety of settings.
4. Identify the surface processes that lead to weathering and erosion in deserts.
5.Describe the role wind plays in sculpting the desert landscape and the features it creates.
6.Explain how human activities such as cultivation and overgrazing pose a serious environmental threat in many parts of the world, resulting in the creation and expansion of deserts.
