A naitural airch produced bi the erosion o differentially wathered rock in Jebel Kharaz, Jordan

Erosion is the process bi which soil an rock are removed frae the Yird's surface bi exogenetic processes such as wind or watter flow, an then transported an deposited in ither locations.

While erosion is a naitural process, human activities hae increased bi 10-40 times the rate at which erosion is occurrin globally. Excessive erosion causes problems such as desertification, decreases in agricultural productivity due tae land degradation, sedimentation o watterways, an ecological collapse due tae loss o the nutrient rich upper soil layers. Watter an wind erosion are nou the twa primary causes o land degradation; combined, thay are responsible for 84% o degradit acreage, makin excessive erosion ane o the maist signeeficant global environmental problems.[1][2]

Industrial agricultur, deforestation, roads, anthropogenic climate chynge an urban sprawl are amangst the maist signeeficant human activities in regard tae thair effect on stimulatin erosion.[3] However, thare are mony prevention an remediation practices that can curtail or leemit erosion o denudit soils.
