2.They mostly occur across central and eastern parts of the United States.
Which of the statements given above is/are correct
Answer: B
Notes:
Statement 1 is incorrect: A derecho is a widespread, long-lived, straight-line windstorm that is associated with a band of rapidly moving showers or thunderstorms.
Straight-line storms are those in which thunderstorm winds have no rotation, unlike a tornado. These storms travel hundreds of miles and cover a vast area.
Statement 2 is correct: They mostly occur across central and eastern parts of the United States. However, Derechos have also been documented elsewhere across the world such as in Germany, and Russia.
