1 Hamartia: Many people who discuss tragedy often mention the hero's 'fatal' or 'tragic flaw.' However, Aristotle would never accuse a hero of such a personal defect. 2  Instead, he asserted that they were guilty of hamartia, or missing the mark.
Floodplains are landscapes shaped by running water. As streams and their larger forms, rivers, flow across the surface of land, they transport eroded rock and other material. (Erosion is the gradual wearing away of Earth surfaces through the action of wind and water.)
Section Summary â¢ Sediment forms several types of deposits, such as deltas, alluvial fans, and floodplains. â¢ A delta is a fan-shaped deposit of sediment that forms where a river meets a large body of water. â¢ Alluvial fans can form when a river deposits sediment on land. â¢ Flooding brings rich soil to farmland and may cause a stream to change course. â¢ Flooding can also lead to property damage and death.
