In which regions are ring porous woods found in trees?

Explanation

**Step-by-Step Solution:**

1. **Understanding Ring Porous Wood**: Ring porous wood is characterized by having large vessels in the early wood (spring wood) and smaller vessels in the late wood (summer wood). The large vessels allow for efficient water conduction during the growing season.

2. **Identifying Regions**: Ring porous woods are typically found in trees that grow in regions with distinct seasonal changes. These trees experience a significant difference in water availability between seasons, which influences the formation of early and late wood.

3. **Geographical Distribution**: Ring porous woods are predominantly found in temperate regions. These areas have a clear distinction between warm and cold seasons, allowing trees to develop the necessary adaptations for water transport.
