Resistance to weathering,ical weathering (disintegration), the mechanical breakdown of rock without any contributory chemical alteration; chemical weathering (decomposition), which involves often irreversible chemical change; and biological weathering, which is effected by the growth or movement of plants and animals.

Weathering profiles and landform development,physical and chemical properties that vary considerably from the surface downwards. These properties are major influences on slope evolution and landform development and for this reason alone it is important to understand the relationships between weathering and landscape. Weathering profiles may al

Landforms on granitic rocks,es of many types of slopes and are good examples of the whole being greater than the sum of the invididual components. When entire landscapes are considered, additional rock properties become important. Widening the spatial context also leads to the necessity of enlarging the time dimension.

Experimental and theoretical work has been incorporated whenever possible. The rock types looked at in detail have been chosen to emphasize major contrasts. Gra

Rock type and landform assemblages,ns of remote sensing. Also, if specific assemblages are related to rock types, direct comparisons could enable the identification to be made of the rock properties responsible for the distinctiveness. A review of landform assemblages associated with the major rock types together with a brief summary of rock characteristics are now offered.

Rock strength and resistance,inently in any explanation of the interplay between landform evolution and rock type. Erosional agencies attack rock in a variety of ways such as by wear, abrasion, impact, crushing and plucking. The most important rock properties are those which reflect these processes. Rock properties can be grouped into three classes:
