Tree-ring samples can be analyzed for archeological purposes using chronological analysis, behavioral analysis, or climatic analysis. Scientists extract core samples using a borer that's screwed into the tree and pulled out, bringing with it a straw-size sample of wood about 4 millimeters in diameter. The color and width of tree rings can provide snapshots of past climate conditions.4 Sources
