Question 1027Navigation General
70% to passWidely spaced isobars on a weather map indicate _______________.
The correct answer is C) gentle breezes. Widely spaced isobars on a weather map indicate areas of low pressure gradient, which results in gentle breezes. Isobars are lines on a weather map that connect points of equal atmospheric pressure. When the isobars are widely spaced, it means the pressure gradient is low, and this corresponds to lighter, more gentle wind conditions. The other answer choices are incorrect because: A) widely spaced isobars do not indicate a higher probability of tornadoes, which are associated with tighter pressure gradients; B) widely spaced isobars do not necessarily indicate ice, snow, or frozen rain, which are more dependent on temperature; and D) widely spaced isobars indicate the opposite of high winds, which require a higher pressure gradient.
