Dendrochonology is used for determining the age of

Options

A. fossils
B. Rocks
C. Trees
D. Annuals

Answer

**Step-by-Step Solution:**

1. **Understanding Dendrochronology**: Dendrochronology is a scientific method used to date events and changes in the environment by studying the growth rings of trees.

2. **Identifying the Subject**: The question asks for what dendrochronology is used to determine the age of. The options provided include fossils, rocks, trees, and annuals.

3. **Analyzing Each Option**:
- **Fossils**: The study of fossils is known as paleontology, which does not involve dendrochronology.
- **Rocks**: The dating of rocks is done through geochronology, not dendrochronology.
- **Trees**: Dendrochronology is specifically used to determine the age of trees by counting the growth rings.
- **Annuals**: Annual plants complete their life cycle in one year, so they do not have multiple growth rings to analyze for age determination.

4. **Conclusion**: Based on the analysis, dendrochronology is used to determine the age of trees by counting the growth rings formed each year.

**Final Answer**: Dendrochronology is used for determining the age of trees.
