Question

Comparing the heights of the 300-mb pressure surface generally across the southern portion of the U.S. to those along the northern portion on the map, as latitude increases (one moves poleward), the height of the 300-mb surface generally ________. This pattern is consistent with that found at 500 mb. a. increases b. remains constant c. decreases

Answer 1

Answer is "decrease".

Because the mass and radius of the earth decrease from equator to pole that why to maintain isobar or equal pressure height will be decrease.

Height of pressure belts will be decrease as shown in above map from 9600 to 8840.
