What are the relief features of the western cordilleras?

The relief features of the Western Cordilleras include high mountain ranges, deep valleys, steep slopes, and rugged terrain. These features are a result of tectonic activity along the Pacific Ring of Fire, which has led to the uplifting and folding of the Earth's crust in this region. The Andes Mountains, which run along the western coast of South America, are a prominent example of the relief features found in the Western Cordilleras.
