A tragic hero can be defined simply as the protagonist of a tragedy. The Greek philosopher Aristotle, however, endowed this individual with a number of specific characteristics. The first of which is his ability to evoke fear and pity from an audience.
Earthquakes can negatively affect the environment in a number of ways. The initial shock can trigger landslides, displacing soil and leaving the area vulnerable to erosion. Quakes can also stir up dust, pollen, spores, and other material and disburse it into the air.
There are two types of weathering that affect the earth's surface: mechanical and chemical. Mechanical weathering is sometimes called physical weathering and often occurs because of temperature changes on the surface. For example, if enough water seeps into a crack and freezes, it expands. This causes it to work as a wedge and it slowly splits open nearby rocks.
