3.
Where is Tornado Alley?
Correct Answer
A. Between Texas and the Dakotas
Explanation
Tornado Alley is a region in the United States where tornadoes are most likely to occur. It is characterized by a high frequency and intensity of tornadoes. The region stretches from Texas in the south to the Dakotas in the north. This area is prone to tornadoes due to a combination of warm, moist air from the Gulf of Mexico colliding with dry, cool air from the Rocky Mountains. The interaction of these air masses creates the ideal conditions for tornado formation, making Tornado Alley a hotbed for severe weather.
4.
What causes a tornado to form?
Correct Answer
A. Two cold fronts on top of a warm front
Explanation
When two cold fronts converge on top of a warm front, it creates an ideal condition for a tornado to form. The clash between the cold and warm air masses causes instability in the atmosphere, leading to the development of a rotating column of air. This rotation can intensify rapidly and form a tornado. The contrasting temperatures and air masses create a strong vertical updraft, which further fuels the tornado's growth. Therefore, the convergence of two cold fronts on top of a warm front is a key factor in the formation of tornadoes.
5.
Which tornado causes the most damage?
Correct Answer
E. F-5
Explanation
The F-5 tornado causes the most damage. Tornadoes are classified based on the Enhanced Fujita (EF) scale, which ranges from EF-0 to EF-5. An F-5 tornado is the most intense and destructive category, with wind speeds exceeding 200 mph. It can level well-built houses, destroy large buildings, and even lift vehicles off the ground. F-5 tornadoes are extremely rare but have the potential to cause catastrophic damage and loss of life.
6.
What is the difference between a tornado watch and a tornado warning?
Correct Answer
B. In a warning, a tornado has been spotted. In a watch the conditions are right for a tornado
Explanation
In a tornado warning, a tornado has been spotted, indicating that there is an immediate threat to life and property. On the other hand, in a tornado watch, the conditions are favorable for the formation of tornadoes, but a tornado has not been spotted yet. This means that people should be prepared and stay alert for potential tornado activity, but there is no immediate danger.
7.
Where is the best place to go when a tornado is headed your way?
Correct Answer
A. A basement
Explanation
A basement is the best place to go when a tornado is headed your way because it provides a sturdy and enclosed space that can offer protection from the strong winds and flying debris associated with tornadoes. Being underground increases the chances of survival as it reduces the risk of being directly impacted by the tornado. Additionally, basements are typically built with reinforced walls and are less likely to collapse compared to other structures such as trailer parks. Seeking shelter near an open window or in a trailer park would be dangerous as it exposes individuals to the destructive forces of the tornado.
8.
If you are outside without a building nearby where should you go?
Correct Answer
C. To a depression in the ground
Explanation
In case you are outside without a building nearby, going to a depression in the ground would be the safest option. This is because a depression in the ground can provide some level of protection from potential hazards such as strong winds, lightning, or falling debris. It can act as a makeshift shelter, reducing the risk of getting injured or affected by adverse weather conditions. However, it is important to note that seeking proper shelter, such as a sturdy building or a designated storm shelter, is always the best choice in severe weather situations.
9.
What is a Funnel Cloud?
Correct Answer
A. A tornado that hasn't touched the ground
Explanation
A funnel cloud is a type of tornado that has not yet made contact with the ground. It is characterized by a funnel-shaped cloud extending from the base of a thunderstorm cloud, but it does not have a visible debris cloud or a tornado's characteristic destructive winds. Funnel clouds can be dangerous as they have the potential to touch down and become a fully formed tornado, causing damage and posing a threat to people and property.
