Tornado Formation
– A tornado is a violently rotating column of air in contact with and extending
between a cloud (often a thunderstorm cloud) and the surface of the earth.
Winds in most tornadoes blow at 100 mph or less, but in the most violent, and
least frequent, wind speeds can exceed 250 mph.
– Tornadoes, often nicknamed "twisters," typically track along the ground for a
few miles or less and are less than 100 yards wide, though some monsters can
remain in contact with the earth for well over fifty miles and exceed one mile in
width.
– Several conditions are required for the development of tornadoes and the
thunderstorm clouds with which most tornadoes are associated. Abundant low
level moisture is necessary to contribute to the development of a thunderstorm,
and a "trigger" (perhaps a cold front or other low level zone of converging
winds) is needed to lift the moist air aloft.
– Once the air begins to rise and becomes saturated it will continue rising to
great heights and produce a thunderstorm cloud, if the atmosphere is unstable.
An unstable atmosphere is one where the temperature decreases rapidly with
height.
– Atmospheric instability can also occur when dry air overlays moist air near the
earth's surface. Finally, tornadoes usually form in areas where winds at all
levels of the atmosphere are not only strong, but also turn with height in a
clockwise, or veering, direction.
– Tornadoes can appear as a traditional funnel shape, or in a slender rope-like
form. Some have a churning, smoky look to them, and others contain "multiple
vortices" - small, individual tornadoes rotating around a common center. Even
others may be nearly invisible, with only swirling dust or debris at ground level
as the only indication of the tornado's presence.

• Activity! “Bugged Out” Activity
– Please create an animal with many strategies to feed on
plants and survive.
• Insects: Give them specialized mandilbles (teeth-like) or piercing
mouth parts, ability to sequester (absorb) toxins, microbe farms.
• Mammals: Four chambered stomach with gut bacteria, and
grinding teeth.
• Birds: Crushing Mouth Parts, gizzard stones
• Camouflage or give it a form of mimicry
– Batesian Mimicry (Looks like an object or other organism)
– Mullerian Mimicry (Warning Coloration)
• A symbiosis with another organisms
– Ex. Cleaning symbiosis
– Ex. Protective / defensive symbiosis
– Give it a cool common and science name;
• Ex) The Super Ant (Anticus killericus)
– The animal should be well drawn and all of the strategies should be
