Question

Quizplus · Accepted Answer

The Enhanced Fujita scale does classify the majority of tornadoes as "weak," with around 70% falling in the EF0-EF1 range. Only a small percentage fall into the stronger categories.

Answer: B
 The Enhanced Fujita scale has 10 categories, ranging from EF0 (65-85 mph) to EF5 (over 200 mph).

Answer: C
 The Enhanced Fujita scale actually only goes up to EF5, with no category for an F6 tornado. The F-scale system was revised to become the Enhanced Fujita scale in 2007.

Answer: D
 The Enhanced Fujita scale classifies tornadoes based on the intensity of their winds and the damage they cause, rather than the width of their spouts. The width of the tornado can be a factor in determining the overall damage potential, but it is not used as a primary factor in classification.
