Final answer:
The statement that F0 tornadoes are the least common is false; they are actually among the most frequently occurring types of tornadoes and are considered the weakest according to the Fujita Scale. Stronger tornadoes, such as F5, are much rarer but cause catastrophic damage due to their intense wind speeds. Preparation and taking safety measures are vital in the event of a tornado.
Step-by-step explanation:
The statement that Fe tornadoes are the least common tornadoes is false. In fact, according to the Fuji ta Scale, which classifies tornadoes based on their intensity and the damage they cause, Fe tornadoes are among the most common. They are categorised as the weakest tornadoes with wind speeds ranging from 40 to 72 mph (64 to 116 km/h) and typically result in light damage. Tornadoes with a higher rating on the Fujita Scale, like F5 tornadoes with wind speeds above 261 mph (420 km/h), are rarer and cause devastating damage.
Tornadoes are known for their incredible destructive power, descending from clouds in funnel-like shapes that spin violently. They are often formed from severe thunderstorms, particularly super cells. These powerful storms feature rapid rotation, detached from the main cloud base, and can result in winds as high as 500 km/h (approximately 300 mph), the strongest and most devastating being on the lower end of the tornado where the funnel narrows, due to the principle that rotational velocity increases as the radius decreases.
Preparation and Safety Measures
In the event of a tornado warning, implementing a safety plan is crucial. Plan B, which involves boarding up windows and taking cover in a tornado shelter, is a prudent course of action compared to Plan A, which suggests doing nothing. The relative costs of these plans can vary greatly based on the potential for destruction to property and the priceless value of human life.
