Question

Surface wind speeds over most of the coterminous U.S. were generally less than those at several stations from the Dakotas to Nebraska, which reported a speed with one long feather denoting ________ knots.

1. Substantial
2. 40
3. 23
4. 10

Answer 1

The question pertains to interpreting symbols on a weather map, specifically the symbol that indicates wind speed. One long feather on a weather map symbolizes a wind speed of 4. 10 knots.

Step-by-step explanation:

The question pertains to interpreting symbols on a weather map, specifically the symbol that indicates wind speed. Traditionally, on such maps, one long feather denotes a wind speed of 10 knots. So, the wind speeds over most of the coterminous U.S. were generally less than the stations from the Dakotas to Nebraska, which reported a wind speed symbol with one long feather, denoting 10 knots.

The long feather in the weather report represents 90 knots of wind speed. The question mentions that surface wind speeds over most of the coterminous U.S. were generally less than those in the Dakotas to Nebraska, and those stations reported a speed with one long feather. Based on the information provided, it can be inferred that the long feather represents a wind speed of 90 knots.
