← Nature & AnimalsWhich outcome occurs during thermal soaring when a raptor encounters rapidly rising air currents?
A)Decreased angle of attack for lift
B)Increased lactate production in muscles
C)Deployment of alula to prevent stall✓
D)Forced molting due to air friction
💡 Explanation
When a raptor encounters strong updrafts, rapid changes in airflow around the wing could lead to stalling, causing the alula (a small group of feathers forming a slot) to deploy, acting as a slat increasing lift and preventing stall. Therefore stall prevention results, rather than decreased attack angle, lactate increase, or forced molting which are driven by different factors.
