Question

Identify the true statement. Choose one:_________ A. Isobars are lines on a weather map that connect places of equal relative humidity. B. Surface winds blow parallel to isobars. C. Winds develop whenever a pressure gradient exists, and they always blow from high-pressure areas to low-pressure areas. D. Areas receiving oblique solar radiation experience more insolation than do areas receiving direct solar radiation.

Answer 1

From the given choices the true statement is Surface winds blow parallel to isobars.

Answer: Option B

Step-by-step explanation:

The winds which flow near the isobars, flow in the parallel direction of the isobars. They are not absolutely parallel to each other but are this much parallel that the purpose of the flight planning can be fulfilled with this.

These winds flow in perpendicular position to isobars which are present at that particular surface and they flow in this direction due to the acting of the force of friction in that area. This force of friction can also change the direction and the flow of the wind.
