In the rainforest, it can take up to 10 minutes for rain to move through
the thick canopy of the trees to the ground.

Tropical rainforests have four layers, each of which has a different
density. The forest floor is the lowest layer, and is usually relatively
sparse due to the lack of sunlight. Above this is the understory layer,
which might be quite dense with large leaves, as shrubs and young trees
compete here for light.
