← Nature & AnimalsWhich airflow consequence results when raptors exploit thermal updrafts?
A)Induced drag marginally increases temporarily
B)Boundary layer remains attached longer✓
C)Turbulence intensity causes flight instability
D)Bernoulli effect decreases lift production
💡 Explanation
Exploiting thermals keeps air attached because soaring leads to increased energy extracting lift using momentum from rising air resulting in prolonged laminar airflow and lift. Therefore attachment increases, rather than decreasing lift, turbulence increases stalling, and drag reduces efficiency.
