1. what hazards/dangers does a tornado pose?
2. what happens during a tornado?
3. how do meteorologists monitor/track this type of weather?
a. what types of tools and/or technology do they use?
4. what are the conditions needed for tornados to occur?

1.) The dangers of tornadoes include flying debris that can destroy property and injure people, and violent winds that lift vehicles and rip off roofs. The primary danger of tornadoes is the flying debris, as this often destroys and injures more than what the winds pick up.
2.) a violent rotating column of air extending from a thunderstorm to the ground. 
3.) They can use radar to track the path of thunderstorms that might produce tornadoes. It is still not possible, however, to detect a funnel cloud by radar and predict its path, touchdown point, and other important details.
a.) Much progress has recently been made in the detection of tornadoes using Doppler radar.Doppler radar is used to detect the motion of raindrops and hail in a thunderstorm, which gives an indication of the motion of the winds. With present technology it is possible to detect the overall storm circulation and even a developing mesocyclone.
4.) Tornadoes form in unusually violent thunderstorms when there is sufficient instability and wind shear present in the lower atmosphere. Instability refers to unusually warm and humid conditions in the lower atmosphere, and possibly cooler than usual conditions in the upper atmosphere.

Hope this is helpful. Did this in geography last year so i had the research.
