Question

which of the following is a major reason for many of the droughts that have affected oklahoma and texas? a. an increase in torrential downpours that result in flooding b. a prolonged shift of the jet stream to the north c. a dramatic decline in autumn thunderstorms d. an increased number of dust storms in southwest oklahoma. please select the best answer from the choices provided

Explanation:

The jet - stream is a key factor in weather patterns. A northward shift of the jet - stream can take away the moisture - bearing air masses from Oklahoma and Texas, leading to drought. Torrential downpours cause flooding, not drought. A decline in autumn thunderstorms is not a major cause of long - term drought. Dust storms are a result of dry conditions rather than a cause of drought.

Answer:

B. a prolonged shift of the jet stream to the north
