2. By the end of class today, you should be able to…
*List different types of severe weather and how they are formed.
*Describe ways to be safe in inclement weather.

3. Thunderstorms
*Thunderstorms form when fast moving warm air rushes upward while fast moving cold air goes downward.
*This friction creates lightning, which creates thunder.

4. Tornadoes
*A tornado is a rotating funnel-shaped cloud that can travel up to 300 miles per hour.
*It extends from a thundercloud to the Earth’s surface.

5. Hurricanes *Hurricanes form over the ocean.
*The warm water causes a low-pressure area above it.
*This air rises, higher pressure air takes its place.
*This movement and change of air pressure causes a spiral movement.
*When the wind speed rises to 119km or more, it is referred to as a hurricane.
*Hurricanes bring heavy rain and strong winds.
