The soils pollution
The soil, origin, nature and degradation
The soil is the surface of the earth’s crust that covers a large part of the continents and islands of the world. It has been formed thanks to the action of abiotic and biotic components for hundreds of millions of years by the mechanical dissolution of rocks, the incorporation of particles and substances from air and water.
Origin, importance and degradation of soils
The origin of soils is closely related to the formation of the earth’s crust. After the cooling and hardening of the Earth’s surface, a process that lasted hundreds of millions of years, soils emerged. Its formation involved the mechanical dissolution of rocks, the incorporation of particles and substances from air and water, but above all the installation of living beings on the planet, almost from the beginning. Soils are mostly biologically active.
