Why are rainforests near the equator?
Show answer & explanation
Answer: Rising air causes heavy rainfall
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.
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.
