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.
What is an earthquake? This can be something of a confusing question, because the answer can be either one of two directly related phenomena, and both involve movements in the Earth's crust. An earthquake is the ground motion you experience when a part of the Earth's crust shifts along a surface, a sort of fracture in the crust, known as a fault. This shift produces vibrations in the rocks and soil beneath us.
