Explanation:
Scientist use trees a whole lot to look at climate of the past by examining tree rings.
These are layers of cambium in each successive years formed. They have an annual growth pattern and are known as tree rings.

- These three rings can be used to interpret climatic patterns.
- During a wet climate, the tree rings are more robust and bigger.
