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 rift valley is formed when pieces of the Eaâ¦rth's crust move apart from each other. V-shaped valleys are formed by the erosive effects of running water and U-shaped valleys are formed by the erosive effects of flowing glacial ice. Rift valleys occur as lithospheric plates are diverging, creating a gap between land masses which is being infilled with rising decompression melted basaltic magma and lava.
