wunder beta🌳 The Amazon rainforest and the river that feeds it
Follow water from the Andes to the Atlantic and see how tributaries, flood pulses, transpiration, clouds, wildlife, and people connect the Amazon rainforest to its river.
What you’ll learn
- From Andes to AtlanticTrace the Amazon from Andean headwaters through its branching basin to the Atlantic delta.The Amazon is a connected drainage network whose tributaries, discharge, and estuary reveal the scale of its basin.
- Forest makes rain travelDescribe transpiration, atmospheric moisture transport, and the forest’s role in regional rainfall.Trees return water to the atmosphere, helping connect forest, clouds, rainfall, and rivers.
- Flood pulse and living riverConnect seasonal flooding, sediment, food webs, transport, and human life along the river.The river’s changing level creates habitat and livelihoods, carrying nutrients and materials between forest, channels, floodplains, and coast.
Questions this course answers
What does the term river basin include?
A basin includes slopes, streams, tributaries, wetlands, and other routes that send water toward a common outlet.
Put these parts of the Amazon water cycle in a sensible sequence.
Water moves from rain into soil and plants, then back to the atmosphere before condensation and later rainfall.
Why can seasonal flooding be important for Amazon wildlife?
Seasonal flooding changes access to habitat and resources rather than simply destroying them.
Why is it misleading to study the rainforest and river as separate topics?
Rain and runoff feed the river, while vegetation and floodwaters alter the movement of water and life through the basin.
