1. Fast Changes Foldable
Earth Science

2. Hurricane How: low pressure area in the ocean
Winds 39mph and higher: tropical storm
Winds 74mph and higher: hurricane
Where: above warm ocean water
Results: Flooding, Rain, Strong Waves, Winds, Beach Erosion
Precautions: move to high ground, tie down loose objects or move them inside, tape/board up windows and stay away from windows

3. Tornado How: within a severe thunderstorm High speed spiral winds
Warm/moist air rises and meets colder air
Where: Midwestern States
Results: tear down houses, devastates communities, wraps cars around trees
Precautions: basement (if you have one), cover head, move away from loose objects, move away from windows

4. Lightning/Thunderstorm
How: moist air rises and begins to cool
Water falls (precipitation), pulling cold air with it
Thunderhead clouds
Where: Everywhere
Results: flooding, lightning, hail, winds, possible tornado
Precautions: stay inside, stay away from tall objects

5. Earthquake How: Earth’s plates move (along fault line)
Where: where 2 plates meet
Example: San Andreas Fault in California
Results: can build up or destroy land, homes and communities are destroyed, ground cracks, can cause tsunami (giant ocean wave) if eruption is under water
Precautions: take cover under heavy desk, table, or in a doorway; avoid falling objects

6. Volcano How: magma pushes up through cracks in Earth’s crust
Where: wherever there is a volcano (could contain weak spots)
Results: eruption from volcano causing lava to flow out, destroys communities
Precautions: none – evacuate when there is an eruption

7. Blizzard How: violent snow storm produced by cold air and moisture
Where: anywhere there is cold air and moisture
Results: a lot of snow
Precautions: stay inside, stay off the roads

8. Flooding How: caused by large amounts of water going on land
Where: anywhere there is a lot of rainfall or ocean surge
Results: destroys land and houses
Precautions: watch for rising water and stay away

9. Landslide/Mudslide
How: caused by force of gravity pulling down rocks, soil, and mud
Where: anywhere there has been a lot of rainfall
Results: destroys hills, cliffs, and houses
Precautions: stay away from unstable land
