â¢ Erosion and deposition are continuous geological processes that are natural and result in relief features seen over the surface of the earth. â¢ If erosion is seen as a sequence of events, deposition takes place at last when the rock particles finally settle down on the surface of earth.
Erosion processes are usually considered under four distinct categories: 1  Mass Wasting: the processes that occur on slopes, under the influence of gravity, in which water may play a part, although water is not the main transporting medium. Mass wasting, or landsliding (see below), processes are very important in Hong Kong (Figure 8).
