and inform the development of technologies to mitigate their effects. |
Emphasis
is on how some natural hazards, such as volcanic eruptions and severe

others, such as earthquakes, occur suddenly and with no notice, and thus are
not yet predictable. Examples of natural hazards can be taken from interior
processes (such as earthquakes and volcanic eruptions), surface processes

hurricanes, tornadoes, and floods). Examples of data can include the
locations, magnitudes, and frequencies of the natural hazards. Examples of

or forest fires) or local (such as building basements in tornado-prone
regions or reservoirs to mitigate droughts). |

qualitative comparisons of forces, mass and changes in motion (NewtonÕs
Second Law), frame of reference, and specification of units. |
