Test Yourself To Know About Tornado: Trivia Quiz!

The United States typically experiences over 1,000 tornadoes in a year. This high number is due to the country's unique geography and weather patterns, such as the collision of warm, moist air from the Gulf of Mexico with cool, dry air from Canada. These conditions create the ideal environment for tornado formation. Additionally, the vast size of the United States provides ample space for tornadoes to occur in various regions throughout the year.

To ensure tornado safety, it is important for house walls to be securely attached to the foundation. This is because the foundation provides a stable and strong base for the entire structure, allowing it to withstand the strong winds and potential impact of a tornado. Attaching the walls to the foundation helps prevent them from being easily blown away or collapsing during a tornado, enhancing the overall structural integrity of the house and protecting its occupants.

When a tornado hits, the strong winds can cause buildings and structures to collapse. This can result in serious injuries for people who are inside or near these structures. Flying debris is a common cause of injuries during a tornado, but collapsing structures pose an even greater risk as they can cause more severe and life-threatening injuries. Therefore, collapsing structures are the main cause of injuries when a tornado strikes.

Tornadoes generate the strongest winds on Earth. These violent and destructive storms are characterized by a rotating column of air that extends from a cumulonimbus cloud to the ground. Tornadoes can reach wind speeds of up to 300 miles per hour, causing significant damage to structures and the environment. Unlike hurricanes, which are larger and longer-lasting weather systems, tornadoes are more localized and typically last for a shorter duration. Earthquakes and thunderstorms do not generate winds as strong as tornadoes.

In a violent tornado, the eye is the calm center where the air pressure is lowest. The correct answer, "Non-Swirling Air," flows into the eye from the top. This non-swirling air helps to maintain the calmness and low pressure in the eye of the tornado, while the surrounding air is swirling rapidly.

A rotating updraft is usually responsible for a tornado in a generating thunderstorm. This is because a tornado forms when there is a rotating column of air within the storm. The updraft creates a strong upward flow of warm, moist air, which then begins to rotate due to wind shear. As the rotation intensifies, it can lead to the formation of a tornado. The other options, such as the anvil, upper level wind, and mammatus clouds, may be present in a thunderstorm but are not directly responsible for tornado formation.

In a multiple-vortex tornado, the multiple vortices can extend into the cloud base. This means that they can reach up into the lower part of the storm cloud where the tornado is forming. The vortices are powerful rotating columns of air that are generated within the larger tornado, and they can reach heights of several hundred feet. However, they do not go as high as the cloud tops or into orbit.

A strong tornado typically has a rough texture on the funnel surface. This is because tornadoes are violent and destructive storms that generate powerful winds and turbulence. The strong winds within a tornado can cause debris and objects to be thrown around, leading to a rough and chaotic surface on the funnel. The rough texture is a result of the intense forces and swirling motion within the tornado.

The correct answer is the Enhanced Fujita Scale. This scale is used to name tornado intensity strengths. It was developed in 2007 as an update to the original Fujita Tornado Scale. The Enhanced Fujita Scale categorizes tornadoes based on the damage they cause, ranging from EF0 (weak) to EF5 (violent). This scale takes into account the type of structures affected, the degree of damage, and estimated wind speeds. It provides a standardized way to measure and communicate the intensity of tornadoes, helping to assess their impact and improve safety measures.

Tornado intensity is commonly measured by analyzing the damage caused by the tornado. This involves assessing the extent of destruction, the type of structures affected, and the overall impact on the affected area. By studying the damage pattern, experts can estimate the wind speed and intensity of the tornado. This method is often used when direct measurements are not possible or available.

Three-second wind gusts for tornadoes are estimated from the point of damage. This is because the intensity of a tornado can be determined by assessing the damage it causes. By analyzing the destruction and patterns of damage, meteorologists can estimate the wind speeds that would have been required to cause such damage. Therefore, the point of damage is a crucial reference point for estimating the wind gusts associated with tornadoes.

Mobile homes are dangerous in tornadoes because they are not built to withstand strong winds. Their lightweight construction and lack of a solid foundation make them vulnerable to the powerful forces of a tornado. As the tornado passes over, the strong winds can easily tear apart the structure, causing it to collapse and potentially injure or trap those inside. This is why mobile homes are considered unsafe during tornadoes compared to more sturdy and well-constructed buildings.

Tornado formation is closely linked with wind speed. This is because tornadoes require a strong updraft of air to start rotating and form a vortex. High wind speeds create the necessary conditions for the formation of tornadoes. As the wind speed increases, it can create a rotating column of air, which can then develop into a tornado under the right atmospheric conditions. Therefore, wind speed plays a crucial role in the formation of tornadoes.

Researchers started trying to replace the Fujita Scale for tornadoes in 2004.
