Question

Quizplus · Accepted Answer

Southeast Asia receives a large amount of rainfall primarily due to monsoons and the Intertropical Convergence Zone (ITCZ). Monsoons bring seasonal winds that carry moisture from the ocean, leading to heavy rainfall. The ITCZ, a region where the northeast and southeast trade winds converge, shifts with the seasons, bringing heavy rains to the region as well.
