8. Science Thoughts 11/30
Why is warm air less dense than cold air? Molecules have more energy so moving more and need more space. Same mass, bigger volume means less density.

9. Severe Weather Notes Type of storm What is it? How does it form?
What are the dangers?
Draw a diagram of the storm
Blizzard/
Winter Storm
Flood
Hurricane
Thunderstorm
Tornado
Precipitation freezes and falls as snow, sleet or rain. 3 keys – cold air, moisture, lift
Flooding, avalanche, ice jams
Severe storm in the winter that can last for several days
A rapid rise of water along a stream or low lying area
Death, cars swept off road, water damage
Heavy rain, dam/levee break, ice melt
Organized rotating weather system, develops in tropics
Heat and energy contact warm waters, wind spirals
Flooding, high winds, storm surge
3 keys: Moisture, unstable air, lift.
Lighting, thunder, hail
Flooding, fires
Violently rotating column of air extending from cloud to the ground
Change in wind direction creates horizontal spinning effect
High winds, trees uprooted

11. Science Thoughts 12/01
Most severe weather is caused by (high/low) pressure masses. LOW hurricane: air pulls UP moisture, Coriolis effect bends thunder/winter/tornado: warm moist air shoots up when hit by a cold front
