← Nature & AnimalsWhich outcome occurs when a soaring bird encounters an atmospheric temperature inversion during migration?
A)Increased soaring efficiency and lift
B)Decreased air sac volume control
C)Reduced atmospheric turbulence intensity
D)Impaired thermal updraft formation airspeed✓
💡 Explanation
When a soaring bird encounters a temperature inversion, convective circulation diminishes because the warm air needed for thermal updrafts is trapped below cooler air, reducing air density, and therefore lift generation. Therefore impaired updraft formation results, rather than increased soaring, air sac volume control, or turbulence reduction, that inversions normally counteract.
