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.)
Truncated (cut off) ridges and hanging valleys form when small valley glaciers merge with a single large valley glacier. Valley glaciers erode V-shaped stream valleys into much more rounded or U-shaped valleys. Sometimes a small lake called a tarn will form at the bottom of the cirque. There are three tarns in a small area of Cumbria, UK, on the geological map below, they are the black shapes.
