Scientists can examine and test the rings to uncover years, even centuries, worth of knowledge about climate, atmospheric changes, and local geography.

Why Do Trees Uproot?

If you’ve ever tried to remove a tree or clear a stump, you know that these plants can have extensive root systems that cling tenaciously to the soil around them. So why do we see so many stories of trees uprooted by storms? Here are some reasons.
