Soils retrogression and degradation
https://www.cs.mcgill.ca/~rwest/wikispeedia/wpcd/...- The destruction of the vegetation implies the destruction of evoluted soils, or a regressive evolution. Cycles of succession-regression of soils follow one another within short intervals of time (human actions) or long intervals of time (climate variations). The climate role in the deterioration of the rocks and the formation of soils lead to the formulation of the theory of the …
