Beginning of earth element

Soil derived from weathering of rocks with the help of the organism, form a uniquebody that covers the rock. The process of land formation known as the''''pedogenesis.The process of this unique form of land as a natural body consisting of layers is calledthe horizon or the ground. Each horizon tells about the origin and processes ofphysics, chemistry, and biology that has traversed the body of land.
Hans Jenny (1899-1992), a soil expert from Switzerland who work in the UnitedStates, said that the soil formed from parent material that has been modified /weathering due to the dynamics of climatic factors, organisms (including humans),and relief of the earth's surface (topography) over time. Based on the dynamics of the five factors are forming various types of soil and land classification can be done.
