Erosion happens when an agent like flowing water carries away soil and rocks that make up the mountain. If you've ever built a sand castle and dumped water on it, you've witnessed erosion: the moving water causes some of the sand to wash away and your sand castle becomes smaller. Erosion comes in two forms: There’s degradation, which is a gradual erosion of the quality of the soil, and there’s loss of soil particles. Run-off from heavy spring or summer rainfall is not the only face of erosion — wind can just as easily blow soil particles down a slope.

Soil erosion is of special concern in agricultural lands, but agriculture is only one of many development activities that greatly accelerates soil erosion processes.

Present rates of erosion are particularly high due to more mountain building and higher mountains than usual in earth's history. (Erosion slows as mountains lose elevation.)

The traditional view has focused on carbon dioxide (CO 2) drawdown by silicate The rise of new mountain chains will directly influence the climate at a regional scale, therefore leading to erosive processes in the changing area. Chemical weathering and water erosion will dominate the humid side, while wind and physical erosion will be more important on the dry areas. 2013-12-18 · We find that mountain erosion rates have increased since about six million years ago and most rapidly since two million years ago. The increase of erosion rates is observed at all latitudes, but is Erosion rates are significantly higher (2–7mmyr21) in several tec- tonicallyactivemountainousareas(Fig.1)(forexample,theSouthern AlpsofNewZealand,Taiwan,PapuaNewGuinea,theHimalayasand the St Elias Range of Alaska). These orogens also receive significant precipitation7, which can sustain high erosion rates. Erosion happens when an agent like flowing water carries away soil and rocks that make up the mountain.
