Kimyoviy nurash. Tog’ jinslari va ayrim minerallar suv va atmosferadagi kislorod hamda karbonat angidridi (СО2) ta’sirida kimyoviy o’zgaradi, yangi birikmalar va minerallar hosil bo’ladi. Bu xildagi jarayonga kimyoviy nurash deyiladi.

CHemical weathering . Some of the rocks and minerals , water and atmospheric oxygen and carbon dioxide ( CO2 ) , the influence of the chemical changes , new compounds and minerals . This kind of process of chemical weathering .

Biologik nurash. Tog’ jinslari va minerallar turli organizmlar (mikroorganizmlar, o’simlik va hayvonot organizmlari) va ularning hayoti tufayli vujudga kelgan mahsullar ta’sirida mexanikaviy ravishda parchalanadi va kimyoviy o’zgarish yuz beradi. Organizmlar ta’sirida yuzaga keladigan ana shunday o’zgarishlarga biologik nurash deyiladi.

Biological weathering . Rocks and minerals of various organisms ( microorganisms , plants and animals ) , and they came into existence due to the life of the product down the influence of mechanical and chemical changes . The influence of such biological changes caused by weathering .

Tuproq – bu nurash po’stlog’idan gumusning mavjudligi, o’ziga xos morfologiyasi, iyerarxik strukturasi, global funktsiyasi bilan farq qiladigan spetsifik biokos tabiiy jismning yangi yaralmasi natijasidir.

The presence of soil erosion rind humus kind of morphology , the hierarchical structure of the global function with different specific How natural substance is the result of the new damned

Har bir tuproq gorizonti o’zining qalinligi, morfologik belgilari shuningdek, fizikaviy xossalari, mexanik, kimyoviy va mineralogik tarkiblari bilan farqlanadi. Mvayyan tuproq gorizonti shu tuproqning kelib chiqishi va rivojlanish tarixini aks ettirganligi uchun xam V.V.Dokuchaev bu qatlamlarni genetik gorizontlar deb ataydi.

Each soil horizon of its thickness , as well as morphological signs of physical properties , mechanical , chemical and mineral content of the letter . Certain soil horizon , reflecting the history of the origins and development of the land also called V.V.Dokuchaev layers of genetic horizons .

Tuproq profili - tuproq genetik gorizontlarining vertikal yunalish buyicha mvayyan tarzda almashib turishi natijasida yuzaga keladigan tashqi qiyofasidir.

The soil profile - genetic soil horizons in the vertical direction may arise in particular as a result of the sharing of exteрНal appearance .
