Question

remains in place. when air remains in place, it can take on the features of the source region. for example, air that remains over a warm source region can increase in temperature as the air gains thermal energy from earths surface. the map below shows wind speeds in earths lower atmosphere on march 1, 2017. two areas, labeled a and b, are outlined on the map. data source: united states national oceanic and atmospheric administration/earth system research laboratory, physical sciences division based on the wind speeds measured this day, which area was more likely to be an air mass source region? area a area b

Explanation:

Air mass source regions require air to remain relatively stationary to take on the region's characteristics. Lower wind speeds mean air is less likely to move, so it can stay in place. Area A has lighter (paler) shading on the map, corresponding to lower wind speeds (closer to 0 m/sec) compared to the darker, higher-wind-speed shading of Area B.

Answer:

Area A
