Trees

This 12-question quiz covers trees, from how they are defined to the role they play in nature.

You will answer prompts such as A young tree is also known as a ___. and What part of a tree indicates its age?

A neat fact tucked into the quiz is that a tree's age is written right inside its trunk. The growth rings you see in a cross-section add up year by year, so counting them tells you how old it is.

Recommended level: intermediate.
