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.)
A delta is formed when sediments and mud from a large river meet the salt water of a sea or ocean. It can be described as a low tract of alluvial land. Deltas often change in size based on ocean and river currents. A delta forms a mouth at the end of a lake.This makes it to where the lake can flow into the ocean. delta is formed when sediments and mud from a large river meet the salt water of a sea or ocean.
