Identify the true statement. choose one:
a. isobars are lines on a weather map that connect places of equal relative humidity.
b. winds develop whenever a pressure gradient exists, and they always blow from high-pressure areas to low-pressure areas.
c. areas receiving oblique solar radiation experience more insolation than do areas receiving direct solar radiation.
d. surface winds blow parallel to isobars g.

Option C is false.

Explanation:

The angle of solar radiation directly affects the increase or decrease in temperature in an area.

When the sun strikes its rays directly (or close to a 90° angle) the solar radiation it's concentrated in a small surface area greatly increasing its temperature.

On the contrary, when solar rays strike the earth at higher latitudes, the radiation concentrates in a far larger area, spreading its heat, and thus, the increase in temperature is lower.
