A scientist in Northern California is studying the tree rings of a very old redwood tree. He notices that the oldest tree rings are very narrow. As the rings move away from the center, he observes 15 rings that get wider and wider.
What can you determine about the climate during the 15-year period during which the tree rings grew wider?
The climate was warmer and wetter.
The climate was warmer and drier.
The climate was colder and drier.
