  2. Questions • What are the natural hazards that come with geography of an area? • Where is the best place to build your stronghold?

  3. Flood • Def-when water overflows onto normally dry land • Can occur slowly or quickly • Flash flood-floods that occur quickly • Can be a wall of water carrying rocks, etc. • Anywhere, esp. low-lying areas, near water, downstream from a dam.

  4. Tsunami (Tidal Wave) • Def-series of waves created by underwater disturbance • E.g: earthquake, landslide, volcanic eruption, meteroite • Coastal areas prone • Dangers: drowning, flooding, water contamination, fires • Safest place to be, in deep ocean

  5. Hurricane • Def-huge storm with minimal winds of 75 mph • Causes damage from flying trash, storm surges, flooding, mudslides, etc • Atlantic Coast, Gulf of Mexico, U.S. prone

  6. Tornado • Def-tube of violent spinning air that touches ground • Winds up to 300 mph • Occur near edge of thunderstorms • “Tornado Alley”-Midwest U.S.

  7. Earthquakes • Def-sudden, rapid shaking of earth • Caused by breaking and shifting of earth’s crust • Can cause tsunami, property damage • West Coast U.S. prone, some in Central U.S.

  8. Volcano • Def-mountain that spews out molten rock • Lava flows destroy anything in its path • Volcanic ash can destroy forests, kill people due to quick spread

  9. Landslide • Def-masses of rock, earth, debris (trash) move down a slope • Can move large bolders, cars, destroy buildings, roads
