Which dense equatorial forest receives heavy rainfall year-round?

The dense equatorial forest that receives heavy rainfall year-round is the tropical rainforest.

Tropical rainforests generally occur near the Equator, where warm temperatures and rising, moisture-laden air produce frequent rainfall. In the strictest ecological sense, a true tropical rainforest has no substantial dry season. Its layered structure includes emergent trees, a closed canopy, an understory, and a dim forest floor.

Constant warmth and moisture support extraordinary biodiversity, but they do not necessarily create rich soil. Heavy rain can leach soluble nutrients downward, while rapid decomposition means many nutrients are held in living plants and leaf litter rather than deep soil. Buttress roots help large trees remain stable and collect nutrients near the surface.

Temperate rainforests are also wet, but they occur outside the tropics and usually have cooler seasonal climates. Montane forests grow at elevation, while bamboo forest describes vegetation dominated by bamboo rather than the broader climate-defined biome.
