Tree-ring dating

Tree-ring dating, also known as dendrochronology, is a method used to determine the age of timber by examining the growth rings in a tree. Each year, a tree adds a new layer of wood, creating rings that vary in width depending on environmental conditions like climate and rainfall. By comparing these patterns of rings in wood samples to a known reference chronology, scientists can accurately date when the tree was alive. This technique helps archaeologists, geologists, and climate scientists understand historical events, environmental changes, and the timing of human activities.
