Not surprisingly, early explorers in deserts, particularly Europeans travelling in the Sahara from the late 18th century onwards, were impressed by, and reported on, the unusual features of these areas. Rock pedestals, sand dunes, and bare-rock hills rising

Elementary Theory of Semiconductors,e and the landforms with which they are generally associated. Invariably, however, such reviews – especially if orientated towards students – deal primarily with perceived certainties. In reality, weathering studies continue to be characterized more by uncertainties and gaps in knowledge – especiall

This chapter focuses on the morphology, chemistry, mineralogy, and origin of the major types of crusts found in dryland environments. Particular attention is given to

Badlands appear to offer in a miniature spatialscale and a shortened temporal scale many of the processes and landforms exhibited by more normal fluvial landscapes, including a variety of slope forms, bedrock or alluvium-floored rills
