Surface weather maps show: a. the pressure at 2 meters above the surface b. the pressure at mean sea level c. the pressure at the surface where the barometer is located d. the pressure at 500 hpa

Option (C)

Explanation:

Surface weather maps are usually defined as a specially constructed map that determines the weather conditions over a particular geographical extent at a particular time from the weather stations.

This map provides the details about the various weather elements such as the temperature range, highest and lowest temperature in a day, humidity content in the prevailing air and the atmospheric pressure.

This map is comprised of various colors and symbols, which helps in the proper identification of places such as the region of high and low pressure, warm and cold front.

Thus, the surface weather maps actually determine the pressure at the surface where the barometer device is placed.

So, the correct answer is option (C).
