Document Summary
Ch. 1 learning goals: explain what density is and how it relates to stratification, explain why disaster scales are based on the. An object"s density is its mass divided by its volume, the amount of space it occupies. Stratification refers to the fact that less dense materials will float on top of denser materials. If a regular graph is used, it is off-scale and becomes an exponential curve. If it is logarithmic, the graph is linear, easier to read, and more accurate. The more intense a natural disaster, the less frequently it occurs. The return period is the average number of years between disasters of the same magnitude (m), calculated by dividing the time span of the data by the number of disasters of same magnitude. Diffuse solar radiation causes heating of air and the ocean, which evaporates water and concentrated into wind circulation, causing hurricanes.
