← Nature & AnimalsWhich mechanism powers thermaling behavior minimizing flapping energy?
A)Differential solar radiation creates eddies✓
B)Decreased lift avoids stall regions
C)Higher viscosity layers enable climbing
D)Induced drag prevents thermal escape
💡 Explanation
Thermals form when differential solar radiation heats the ground unevenly, the resulting **buoyancy effect** produces rising air columns birds use for soaring; because thermals concentrate upwards rather than laterally. Therefore increased available potential energy, avoiding frequent wing flapping.
