an impassable dense forest (typically tropical)

The jungle is a place in a rainforest where the forest floor is covered with plants. Like other rainy places, they have many rivers or streams. Scientists think that more types of animals and plants live in the jungles than everywhere else. When people talk about jungles, they sometimes mean the whole rainforest.

The crowding in a jungle leaves little room to walk. This may make it dangerous to people. However, it also has benefits. The many plants and animals can provide food for foraging.

The Amazon rainforest is thick and dark jungle in many places in nine countries. However, most of this forest is in Brazil, South America.
