precipitation, less than enough to
support growth of most plants.
3. DESERTS
Deserts are defined as areas with an
average annual precipitation of less than
250 millimetres (10 in) per year.
4. DESERTS
Deserts are often composed of sand and rocky
surfaces. Sand dunes called ergs and stony
surfaces called hamada surfaces compose a
minority of desert surfaces. Exposures of rocky
terrain are typical, and reflect minimal soil
development and sparseness of vegetation. The soil
is rocky because of the low chemical weathering.
