← GeographyWhich outcome results when an air mass moves poleward in Northern Hemisphere at high speed?
A)Deflection to the east due to Coriolis✓
B)Increased density due to adiabatic cooling
C)Stabilization of atmospheric stratification
D)Formation of a low-pressure system
💡 Explanation
When a North Hemisphere air mass moves poleward, the Coriolis effect causes deflection to the east because Earth's rotation influences moving objects depending their latitude, increasing with speed. Therefore eastward deflection resuts, rather than other effects dependent on thermal process or stability parameters.
