Document Summary

Any consideration of natural disaster or catastrophe deals with energy; two energy sources are possible: energy internal to earth and energy external to earth. Earth"s internal heat energy is responsible for processes that lead to such things as earthquakes, tsunami and volcanic eruptions; energy from outside earth produces hurricanes, climate changes and asteroid impacts. In this course, we will deal with all those processes providing examples from. Here and there through the course, i make brief reference to the scientific method" or the scientific approach". To clarify, i"ll quickly run through the process involved in those concepts. The idea is that everyone starts with one or more observations, and consciously or unconsciously then forms a hypothesis. Over time, more and more observations will test that hypothesis, and eventually either they suggest your hypothesis was correct (i. e. it passes the tests), or the hypothesis was wrong and you start over.
