The age of tree is calculated by counting annual rings is called

Options

A. Dendrochronology
B. Ageing
C. Chronology
D. chorology

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the method used to determine the age of a tree by counting its annual rings.

2. **Identifying Key Terms**: The term "annual rings" refers to the growth rings formed in the trunk of a tree, which indicate the age of the tree. Each ring typically represents one year of growth.

3. **Exploring the Options**: The options provided are:
- a) Dendrochronology
- b) Aging
- c) Chronology
- d) Chorology

4. **Analyzing Each Option**:
- **Option a: Dendrochronology**: This term specifically refers to the study of tree rings and is used to determine the age of trees by counting these rings. It also provides information about past climate conditions.
- **Option b: Aging**: This is a general term that refers to the process of growing older and does not specifically relate to trees or their rings.
- **Option c: Chronology**: This term refers to the arrangement of events in the order they occurred, which is not specific to trees.
- **Option d: Chorology**: This term relates to the study of the spatial distribution of phenomena, which is unrelated to tree age determination.

5. **Conclusion**: Based on the analysis, the correct answer is option a) Dendrochronology, as it is the specific study that involves counting the annual rings of trees to determine their age.

**Final Answer**: The age of a tree is calculated by counting annual rings is called Dendrochronology.
