2) that many geomorphic systems are best understood in terms of the stochasticity of the processes occurring in them, that is, the probability distributions of event magnitudes and return times. [ 42 ] [ 43 ] This in turn has indicated the importance of chaotic determinism to landscapes, and that landscape properties are best considered ...
One of the greatest examples of this feedback between tectonic and climatic interactions may be preserved in the Himalayan front and in the development of the rain shadow effect and the Asian Monsoon. The Himalayas act as an orographic barrier that can impede atmospheric circulation and moving air masses. When these air masses try to move up ...
Mauna Loa is the classic example, with a slope of 4°-6°. (The relation between slope and viscosity falls under the topic of angle of repose . [ 12 ] ) A composite volcano or stratovolcano has a more steeply rising cone (33°-40°), [ 13 ] because of the higher viscosity of the emitted material, and eruptions are more violent and less frequent ...
Nivation hollow – Geomorphic processes associated with snow patches; Palsa – A low, often oval, frost heave occurring in polar and subpolar climates; Permafrost plateau – A low, often oval, frost heave occurring in polar and subpolar climates; Pingo – Mound of earth-covered ice; Rock glacier – Glacial landform
The names of many rivers derive from the color that the transported matter gives the water. For example, the Yellow River (Huang He) in China is named after the hue of the sediment it carries, [7] and the White Nile is named for the clay it carries.
This system uses the dominant geomorphic process or setting to classify different groups of landforms into two major groups, Geomorphic Environments and Other Groupings with a total of 16 subgroups. The groups and their subgroups are not mutually exclusive; landforms, including ridges, can belong to multiple subgroups.
A classic example is the Canadian Shield. During the last ice age, the topsoil was scraped off, leaving mostly bare rock. The melting of the glaciers left land with many irregularities of elevation and a great deal of water to collect in the low points, resulting in the region's many lakes.
Deposition is the geological process in which sediments, soil and rocks are added to a landform or landmass. Wind, ice, water, and gravity transport previously weathered surface material, which, at the loss of enough kinetic energy in the fluid, is deposited, building up layers of sediment.
