Question

Which statement(s) about tornadoes is (are) true?

(a) EF5 tornadoes occur rarely but stay on the ground the longest and cause the most
fatalities.
(b) The most likely time to observe a tornado would be between 5:00 and
6:00 P.M. during the month of May.
(c) Weak tornadoes (EF0 and EF1) are more common than stronger tornadoes
(EF4 and EF5) since the conditions to produce these weak tornadoes are often
found in supercells.
(d) Tornadoes are common in the United States because of its unique geography,
including the Rockies to the west, which help cyclones form; the Gulf of Mexico,
which provides heat and moisture; and the plains of central Canada, where the cold
air originates.
(e) All of the above statements are true.

Answer 1

Statements (c) and (d) about tornadoes are true. Weak tornadoes are more common than stronger tornadoes, and the United States' geography contributes to the common occurrence of tornadoes there.

Step-by-step explanation:

Among the statements provided concerning tornadoes, the accurate statements are:

• (c) Weak tornadoes (EF0 and EF1) are more common than stronger tornadoes (EF4 and EF5) since the conditions to produce these weak tornadoes are often found in supercells, and
• (d) Tornadoes are common in the United States because of its unique geography, including the Rockies to the west, which help cyclones form; the Gulf of Mexico, which provides heat and moisture; and the plains of central Canada, where cold air originates.

Statement (a) is not entirely accurate since the EF5 tornadoes do not necessarily stay on the ground the longest, but they are indeed the most intense and can cause the most fatalities. As for statement (b), while many tornadoes do occur in the late afternoon and early evening, the peak time can vary and is not restricted to 5:00-6:00 P.M. Furthermore, there is no specific month where observing a tornado can be considered most likely, though May is indeed part of the peak tornado season in the United States.

Overall, it is true that stronger tornadoes are less common compared to weaker ones and that the geographic conditions of the United States create an environment that is conducive to the formation of tornadoes.
