| Outline of Final Research Achievements |
This study extracted the summits of the world mountains located between 60°N and 60°S, and evaluated the steepness of world mountains based on the relief and slope around the extracted summits using about 30 m DEMs (digital elevation models). Extremely steep summits, type Ia (reliefs R > 2,000 m, average slopes S > 50°) and Ib (R > 1,500 m S > 45°) were mostly located in the Himalaya Mountains. Several Ib summits were distributed in the Alps, Tianshan and Andes Mountains. Steep summits, Ic (R > 1,000 m, S > 40°) and Id (R > 500 m, S > 35°) were distributed in the mountains of the Alpine-Himalayan belt, Pacific Rim, and Central Asia and African rift valleys. High relief and gentle slope summits, that is, type II (R > 500 m, S < 35°), were distributed in the mountains of the passive margins in addition to type I mountains. Low relief and steep slope summits, type III (R < 500 m, S > 35°), were mostly located in the tower karst region of southern East Asia.
