← GeographyWhich mechanism causes tropical rainforests at latitudes near the Intertropical Convergence Zone (ITCZ)?
A)Orographic lifting triggering cooling
B)Hadley cell-driven atmospheric uplift✓
C)Ocean current moderating temperatures
D)Jet stream convergence destabilizing air
💡 Explanation
When warm, moist air converges at the ITCZ, Hadley cell circulation causes rising air because of converging surface winds, leading to adiabatic cooling and condensation, resulting in precipitation that supports rainforests. Therefore, Hadley cell uplift results, rather than orographic lifting, ocean temperature moderating, or jet stream destabilization which require different conditions to produce the same effect.
