Question

A tree grows in an environment where there are generally four or five years of severe drought followed by a rainy year. How will this affect the tree's growth rings?

Answer 1

Answer:

Dendrochronologists have shown that tree-ring data produce a remarkably accurate history of droughts and other climate changes.

Explanation:

The underlying patterns of wide or narrow rings record the year-to-year fluctuations in the growth of trees. The patterns, therefore, often contain a weather history at the location the tree grew, in addition to its age. In dry environments, such as the Middle East or U.S. Southwest, tree rings typically record wet or dry years, and in cooler areas (high latitudes or high elevation), the ring widths are often a proxy for temperature.
