the warm air up rapidly and produces thunderstorms
\Q\.Which is heavier dry air or moist air? - ANSWERS✔-Dry air
\Q\.What causes lightening? - ANSWERS✔-separation of electrons/charges (base- and top+)
\Q\.What causes thunder? - ANSWERS✔-lightening heats up air, causing a rapid expansion
\Q\.What causes hail? - ANSWERS✔-Thunderstorms. When strong winds push raindrops up into
the atmosphere and cold air freezes them
\Q\.What distinguishes supercell from all other thunderstorms and how do supercell develop? -
ANSWERS✔-Supercell are large thunderstorms that rotate and form strong wind shears that

\Q\.Tornados occur worldwide, how many tornados occur in the US each year? - ANSWERS✔-
1,000 per year

\Q\.That Doppler radar cannot easily measure what - ANSWERS✔-tornado wind speeds
\Q\.Where do you take shelter from a tornado while outdoors? - ANSWERS✔-indoors
\Q\.Where do you take shelter from a tornado while indoors? - ANSWERS✔-in the basement or
a place with little to no windows
\Q\.Where do you take shelter from a tornado while in a car? - ANSWERS✔-drive away at right
angles or in a low spot
\Q\.What is the biggest danger from tornados? - ANSWERS✔-flying objects
\Q\.What can tornados generally pick up? - ANSWERS✔-cars, shudders, barn walls, small or big
animals, trucks
\Q\.Can tornados be generated by wildfires? - ANSWERS✔-yes, they are called fire whirls
