← Nature & AnimalsWhich outcome enhances thermal soaring performance when uneven ground heating creates thermals?
A)Exploitation high wing loading reduces drift
B)Activation of countercurrent exchange in tendons
C)Modulation of feather angle via muscles✓
D)Increased air sac volume enhances lift
💡 Explanation
Modulation of feather angle enhances thermal soaring because it adjusts lift and drag in response to turbulent air; therefore, soaring becomes more efficient, rather than relying solely on wing loading, which affects speed without fine control.
