Why does the Equatorial region have dense vegetation?

The Equatorial region has dense vegetation primarily due to its warm temperatures and high humidity, which create an ideal environment for plant growth. This area receives abundant rainfall throughout the year, often exceeding 2000 mm annually, supporting the growth of diverse flora, including towering trees, vines, and a wide variety of understory plants. Additionally, the consistent sunlight and rich biodiversity contribute to the lushness of the rainforest ecosystems found in this region.
