What major geographical feature is shared by both Switzerland and Italy?

The Alps are a major geographical feature that spans several countries in Europe, including both Switzerland and Italy. This mountain range is renowned for its stunning peaks, diverse ecosystems, and significant cultural importance. The Alps serve as a natural border between many countries and are known for their influence on climate, tourism, and outdoor recreation.

Switzerland is often associated with the Alps, as a large part of the country is located within this mountainous region, which contributes to its picturesque landscapes and tourism industry. Similarly, Italy's northern region, including areas like the Aosta Valley and South Tyrol, is home to some of the most famous peaks of the Alps, making it a popular destination for skiing and hiking.

In contrast, the other geographic features listed, such as the Andes, Rocky Mountains, and Appalachian Mountains, are not relevant to Switzerland and Italy, as they are located in different parts of the world: the Andes in South America, the Rockies primarily in North America, and the Appalachians in the eastern United States. Thus, the Alps are distinctly significant as they are the common mountainous feature shared by both Switzerland and Italy.
