Geography KS3 / GCSE: How does a river change as it travels downstream?

Liz Bonnin introduces BBC archive footage of Sir David Attenborough as he follows the Amazon River downstream.

Sir David explains how the characteristics of a river change and how dramatic scenery results from the erosion of rocks.

He also explains how waterfalls form in the upper course of a river and meanders are found in the lower course.

The formation of ox-bow lakes is also shown.

Sir David Attenborough also talks about the Yellow River in China as well as other major rivers around the world.

This short film is from the BBC series. Physical Geography with Liz Bonnin.
