Deposits of sediment are the leading cause behind the formation of beaches. Where a bay is formed, there may be a headland on one side, extending into the body of water. Parts of the headland that jut out into the water slowly get eroded over time by the mechanical energy of winds and waves. Headland cliffs are cut back by wave erosion and the bays are filled with sand deposits until the coastline becomes straight. So.. Continued wave action causes the widened crack or cave to break through the headland and form an arch. 4) Try Mr G's lights out exercise - look for evidence of weathering and coastal erosion and write the evidence down. The animals were reintroduced into the area in 1963 after having been nearly exterminated by white hunters in the nineteenth century. Caves occur when waves force their way into cracks in the cliff face. The Badlands are cut from deep alluvial and volcanic ash deposits that have been sculptured and carved into fantastic forms by the continuous action of wind and water falling in infrequent but torrential downpours. Stacks are formed by headlands turning into caves, caves turning into arches and arches turning into stacks. Other Indian tribes, such as the once-feared Comanche, who were making a last stand against encroaching white settlers on the southern plains, also embraced these beliefs.
