Summary:The paper discusses four processes that may be responsible for shaping the relief of the comet landscape. The considerations take into account the following phenomena: intense sublimation of cometary ice, emission of dust from the surface comet and through jets, migration of dust on the cometary surface, and destruction of fragment the nucleus surface in the context of a change in cometary brightness. These processes appear to be of key importance for the formation of an irregular comet nucleus structure. It should be remembered that the processes discussed in this paper have an impact on the relief of the surface, but on a longer time scale, i.e., more than a few orbital periods.
