Book 17, Question 77
Why Do Some Rainforest Trees Have Giant Flared Roots Like Walls?
Buttress roots are giant, wall-like ridges that help tall trees stand up! Rainforest soil is thin, so tall trees need extra support. These roots spread out from the trunk like the fins of a rocket.
More fun facts
- These giant flared roots are called buttress roots.
- Rainforests have only a shallow layer of fertile soil.
- Shallow roots alone can't hold up huge rainforest trees.
- Buttress roots help keep the tallest trees from blowing over in strong winds.
