Tree-ring analysis, also known as dendrochronology, is a scientific method of dating archaeological and environmental samples by counting and analyzing the annual growth rings of trees. Tree rings provide a record of past environmental conditions, such as climate and precipitation, as well as indicate the age of the tree and any disturbances that may have affected its growth. This method can be used to date wooden objects, study past climate changes, and reconstruct historical events. Tree-ring analysis is a valuable tool for understanding long-term trends in environmental and climatic changes.
