Eoline Prcesses! |
| EOLINE PROCESSES it is the processes pertain to the activity of the winds & more specifically , to the winds ability to shape the surface of the earth & other planets. winds may erode transport & deposit minerals & are effective agents in regions with sparse vegetation & large supply of unconsolidated sediments . this process are important in arid environments such as deserts . wind erodes the earth's surface by deflation , by the removal of loose, fine-grained particles , by the turbulent eddy action of the wind & by abrasion. regions which experience intense & sustained erosion are called deflation zone. most of Eoline deflation zones are composed of the desert pavement, a sheet-like surface of rock fragments that remains after wind & water have removed the fine particulars, a dark, shiny stain called desert vanish is often found on the surface of some desert rocks that have been exposed at the surface for a long period of time. shine stain minerals are manganese, iron oxides, hydroxides, clay. deflation basins , called blowouts are hollows formed by the removal of particles by wind . wind-driven grains abrade landforms. sculpted landforms , called Yardangs, are up ot tens of meters high & kilometers long are form that have been stremlined by desert winds. |
