Why is humidity high in lower latitudes?

Humidity is high in lower latitudes primarily due to the warm temperatures that lead to increased evaporation of water from oceans, lakes, and rivers. The equator and tropical regions receive more direct sunlight, causing higher temperatures and, consequently, more moisture in the air. Additionally, these areas often experience consistent rainfall and dense vegetation, which further contributes to elevated humidity levels. The combination of these factors creates a humid environment typical of lower latitudes.
