← Nature & AnimalsWhich risk increases when a soaring bird encounters a turbulent atmospheric layer with decreased coefficient of lift?
A)Stall due to boundary layer separation✓
B)Hypothermia due to increased convective heat loss
C)Dehydration due to elevated evaporative cooling
D)Predation due to reduced maneuverability
💡 Explanation
When turbulence decreases the coefficient of lift, the critical angle of attack is reached sooner in soaring birds becausethe smooth airflow past the wing is disrupted, causing premature boundary layer separation and loss of lift. Therefore stalling is a risk, rather than other effects depending on temperature, hydration, or outside predators.
