Both the North Cascades and southern Blue Ridge consist of crystalline rock and both are part of the Hinterland Deformation Belt structural province. Why are the North Cascades so much more rugged than the southern Blue Ridge? Be specific with respect to elevation, relief, precipitation, and glaciation.

Both these regions are part of the deformation belt. Cascades have higher elevation as comaped to blue ridges.

Explanation:

The northern cascades ranges are found along with western North America. They span from the Canadian province to the state of Washington in the U.S and thy include various mountain ranges.  Mount Baker is the most higher range and consists of an elevation of 3,286 meters. Large precipitation terms of snow are found along with the resulting glaciation that is found in the western part of the range. Southern blue ridge is a 9.4 million acre region of ecoregion that is unbroken by a vast expanse of forestlands. They are a part of the larger Appalachian mountain ranges. They comprise of an elevation of 6,684 feet, geological these are granitic metamorphic volcanic formations. The blue ridge consists of highlands and peaks. The blue ridge get s about 1,529 mm of annual rainfall.
