Growth rings are well marked in trees growing in

Options

A. Mumbai
B. Chennai
C. Shimla
D. Kolkata

Answer

**Step-by-Step Solution:**

1. **Understanding Growth Rings**: Growth rings, also known as annual rings, are formed in trees due to the seasonal growth patterns of xylem tissues. They consist of two parts: spring wood (early wood) and late wood (summer wood).

2. **Identifying the Conditions for Growth Rings**: Growth rings are well marked in areas where there are distinct seasonal changes, particularly in temperature and moisture. This allows for a clear differentiation between the growth of spring wood and late wood.

3. **Analyzing the Options**:
- **Mumbai**: This region has a tropical climate with high moisture throughout the year. The lack of distinct seasons means that growth rings are not well marked.
- **Chennai**: Similar to Mumbai, Chennai also experiences a tropical climate with consistent moisture, leading to poorly defined growth rings.
- **Shimla**: Located in a temperate region, Shimla experiences distinct seasonal changes, including colder temperatures and varying moisture levels. This environment is conducive to the formation of well-marked growth rings.
- **Kolkata**: Like Mumbai and Chennai, Kolkata is also in a tropical region with high moisture, resulting in less distinct growth rings.

4. **Conclusion**: Based on the analysis, the region where growth rings are well marked is **Shimla** due to its temperate climate and seasonal variations.

**Final Answer**: Growth rings are well marked in trees growing in **Shimla**.
