← GeographyWhich phenomenon results when a low-pressure system forms?
A)Cyclonic rotation intensifies near poles✓
B)Thermal expansion decreases average salinity
C)Ocean upwelling diminishes quickly instead
D)Glacial calving events form icequakes
💡 Explanation
Cyclones rotate due to the Coriolis effect deflecting winds flowing toward low pressure. This deflection is more pronounced at higher latitudes because the Coriolis effect increases with distance from the equator; therefore cyclonic rotation is strongest at poles rather than salinity changes.
