The study of annual rings of a tree is called

The study of annual rings is called dendrochronology. Dendrochronology is the scientific method of dating trees based on the analysis of their growth rings. Each year, trees form a new ring in their trunks, and the width of each ring can vary depending on environmental conditions such as temperature, rainfall, and soil fertility. By examining these rings, dendrochronologists can determine the age of a tree and gain insights into past climate changes and ecological events. This information is useful in various fields, including forestry, archaeology, and environmental science, as it provides a timeline of historical events and natural occurrences. Dendrochronology also aids in understanding the impact of climate change on forests and ecosystems
