ABSTRACT

In Britain today, it is possible to observe the denudational processes associated with rivers, hillslopes and the sea. Many of these processes produce the familiar shape of the landscape. There are two main reasons for changes in the erosional processes: the relative level of land and sea was not the same as it is today and the climate of Britain was at times hotter and at times colder than it is today. The relationship between land and sea can change either with movements of the land or changes in the level of the sea. The earth’s climate is in a constant state of change. The reasons for such changes appear to be enormously complex and linked largely to changes in the sun itself, although earth surface processes such as volcanic activity appear capable of altering the physical properties of the atmosphere. Melt-water deposits are generally more difficult to identify, although various forms of kame and esker are quite common.
