Question

The natural soil making process is​

Answer 1

Answer:

Soil minerals form the basis of soil. They are produced from rocks (parent material) through the processes of weathering and natural erosion. Water, wind, temperature change, gravity, chemical interaction, living organisms and pressure differences all help break down parent material.

Answer 2

Soil making is a process strongly driven by the boundary conditions for the soil system. One of the key conditions (e.g., initial state in eqn is the physical configuration of the landscape, which dictates the nature of the ‘geomorphic surface’: the atmosphere/land boundary. From a physical perspective, landscapes can be stable, erosional, or depositional. While physical erosion or deposition can be driven by wind and other processes, slope-driven transport dominates many soil-mantled landscapes. From this perspective, the three landsurfaces can be defined as a function of slope and curvature (the change in slope with downslope distance):

•

Stable Landsurface: slope (dz/dx) = 0;

•

Erosional Landsurface: curvature (d(slope)/dx) = (−)

•

Depositional Landsurface: curvature = (+)
