Moutains, valleys and flood plains are three kinds of landforms in a rainforest. Rainforests can also have streams or rivers running through them and wetlands. These are the main types of landforms found in a rainforest. A mountain is a natural elevation of the earth's surface, with a greater height than a hill. Moutains can be found in the rainforests of South America, Asia, Australia, Africa and the Pacific Islands. About 22% of all moutains are found in South America. A valley or dale can be in the shape of a U or a V. The valleys also provides a channel for rivers. The bottom of a valley is generally flat, if the bottom is flat, and large enough the valley could become a flood plain. Flood plains are large, flat areas. These areas are nears rivers and can easily flood. Flood plains are formed by winding streams or intertwined rivers. These plains support the growth of microbes because of the release of nutrients after the plain has flooded. There are many different types of wetlands, they include mashes, swamps and bogs. The soil of wetlands are saturated with water because the wetlands water level is near the ground. Brazil, Chile, Bolivia and Paraguay are some areas where wetlands can be found. A river is different from a stream because of it's size. It also meets up with another body of water like another river and rivers are fresh water unlike oceans or seas. The bed of a river is larger than that of a streams and rivers can carry nutrients that fertilize their beds. Just like streams rivers are connected by channels. A well know river that runs through a rainforest is the amazon river. The amazon river originates in the Andes mountains and ends at the Atlantic Ocean.
