What Do You Actually Know About Tornado? Trivia Quiz

Explanation
The correct answer is "Small" because tornadoes typically have a narrow and compact column of rotating air. This column can vary in size, but it is generally smaller in diameter compared to other options like Extra Large, Medium, or Large. Tornadoes are known for their destructive power, and their small size allows for concentrated and intense winds within the funnel cloud.

Explanation
The correct answer is 1-Feb. The EF Scale, also known as the Enhanced Fujita Scale, was adopted as the standard of tornado intensity in the U.S. on February 1, 2007. This scale replaced the original Fujita Scale and is used to categorize tornadoes based on the damage they cause.

Explanation
Tornadoes are frequently associated with thunderstorms. Thunderstorms provide the necessary atmospheric conditions for tornado formation, including warm, moist air near the surface and strong wind shear in the upper atmosphere. These conditions create a rotating column of air, which can develop into a tornado. While tornadoes can occur in different weather conditions, they are most commonly observed during thunderstorms due to the specific combination of factors needed for their formation.

Explanation
Canada reports the second largest number of tornadoes. While the United States is widely known for its high frequency of tornadoes, Canada also experiences a significant number of tornadoes each year. The geography and weather patterns in certain regions of Canada, particularly the Prairies and the southern parts of Ontario and Quebec, create favorable conditions for tornado formation. Although the number of tornadoes in Canada is lower compared to the United States, it is still the country with the second highest tornado activity in the world.

Explanation
The basement is the best place to stay during a tornado because it is the most secure and offers the most protection. Being underground provides a barrier against strong winds and flying debris. Additionally, basements often have sturdy walls and support beams that can withstand the force of a tornado. This makes it the safest location in the house during severe weather conditions.

Explanation
During a tornado, seeking refuge in a ditch is the safest option. Ditches are lower lying areas that provide some protection from the strong winds and flying debris. By lying flat in a ditch, you can reduce your exposure to the tornado's destructive forces. It is important to cover your head and neck with your arms or a sturdy object to further protect yourself. Seeking refuge in a car, phone booth, or mountain is not recommended as they do not provide sufficient protection from the tornado's powerful winds and debris.

Explanation
T. Theodore Fujita is the correct answer because he was the first person to propose a scale for comparing tornado events. His scale, known as the Fujita Scale or F-Scale, was introduced in 1971 and is still widely used today to measure the intensity of tornadoes based on the damage they cause. Fujita's scale ranges from F0 (weakest) to F5 (strongest), providing a standardized way to classify tornadoes and assess their destructive power.

Explanation
A weak tornado's funnel cloud resembles an upward-opening cone. This means that the funnel cloud of a weak tornado has a shape similar to a cone, but it is open at the top, with the wider end facing upwards. This shape is commonly observed in weaker tornadoes, where the wind rotation is not as strong and the funnel cloud may not reach all the way to the ground.

Explanation
The answer "Two Percent" suggests that only a small percentage of tornadoes are classified as violent. This indicates that out of all the tornadoes that occur, only a very small fraction, specifically two percent, are considered to be violent.

Explanation
Secondary vortices sometimes form in the annulus of a violent tornado. The annulus refers to the ring-shaped region between the outer edge of the tornado and the main funnel cloud. These secondary vortices can form due to variations in wind speed and direction within the tornado, causing rotation within the annular region. These secondary vortices can be smaller in size compared to the main funnel cloud but can still contribute to the overall destructive power of the tornado.

Explanation
The central axis of airflow circulation in a tornado is called the Core Region. This is the area where the strongest winds and most intense rotation occur. It is the part of the tornado that extends from the ground up to the cloud base. The Core Region is responsible for the destructive power of a tornado, as it is where the most damage is typically observed.

Explanation
Researchers classify a tornado using the EF Scale. The EF Scale, also known as the Enhanced Fujita Scale, is a measurement scale used to categorize tornadoes based on the damage they cause. It takes into account factors such as wind speed and the type of structures affected. This scale helps researchers understand the intensity and destructive potential of a tornado, allowing them to better analyze and compare tornado events.

Explanation
Suction vortices are a little-understood feature of tornadoes. These are smaller, rotating columns of air that form within the larger tornado. They are often found near the ground and can cause additional damage by intensifying the winds in localized areas. Despite their significance, suction vortices are not well understood due to the difficulty in studying them directly. Their unpredictable nature and the dangers associated with getting close to a tornado make it challenging for scientists to gather data and gain a deeper understanding of these vortices.
