Tree-ring dating, also known as dendrochronology, is a method used by archaeologists, environmental scientists, and other researchers to determine the age of trees and wooden objects by analyzing the annual growth rings present in their wood. Each year, trees produce a new growth ring made of light and dark layers, which can vary in size depending on environmental conditions such as temperature, rainfall, and soil nutrients. By comparing patterns of growth rings from different trees or wooden samples, researchers can create a timeline of past events and environmental changes. Tree-ring dating is particularly useful for dating wooden structures, artifacts, and paintings, as well as studying past climate patterns and environmental conditions.
