Why are rainforests near the equator?
Show answer & explanation
Answer: Rising air causes heavy rainfall
Rising air causes heavy rainfall ✓ — Correct! At the equator, intense solar heating causes air to rise strongly (convection). Rising air cools, water vapor condenses—heavy rainfall year-round. This creates the Intertropical Convergence Zone (ITCZ). Combined with consistent warmth and rainfall, perfect conditions for rainforest development. Amazon, Congo, and Southeast Asian rainforests all near equator!
Tall trees attract rain clouds — Wrong. Trees don't attract rain. Equatorial rainforests exist because rising warm air creates perpetual heavy rainfall through atmospheric convection.
No seasons means constant growth — Wrong. Lack of seasons helps, but rainforests exist near the equator because rising air there causes year-round heavy rainfall.
