Geologic and geomorphological works on gravitational processes and landforms in mountains mostly deal with movements of slope mantle due to gravitation and more seldom - with gravitation impact on solid rocks near slope surface. It has been established however that the gravitational processes are manifested practically within the whole mass of the ridge. The authors delimit zones of prevalence of different types of gravitational processes; their mechanism is considered and illustrated with cases from the best studied regions (Central Asia and Crimea mountains).
