Although each continent has its special features,all consist of various combinations of components that include shields,moutain belts,intracratonic basins,margins,volcanic plateaus,and blockvaulted belts.The basic differences among continents lie in the proportion and the composition of these features relative to the continent size.Climatic zones have a crucial effect on the weathering and formation of the surface features,soil erosion,soil deposition,land formation,vegetation,and human activities.Moutian belts are elongated narrow zones that have a characteristic folded sedimentary organization of layers.They are typically produced during substabtial crustal movements,which generate faulting and moutain building.When continental margins collide,the rise of a marginal edge leads to the formation of large moutain ranges,as explained by the plate tectonic theory.This process also accounts for the occurrence of mountain belts in ocean basins and produces evidence for the ongoing continental plate evolution
