Due to particles extrusion, crystal lattice deformation expands to the adjacent area, though the deformation strength reduces gradually (Figs. 10(a)-10(other hand, after impacting, the particle may retain to plow the surface for a short distance to exhaust the kinetic energy of the particle. As a result, parts of the free atoms break apart from the substrate and pile up as atom clusters before the particle. The observation is consistent with results of molecular dynamics simulation of the nanometric cutting of silicon [15] and collision of the nanoparticle with the solid surface [16]. 

AU fungi are heterotrophs and are predominantly aerobic, and hence are usually found at or near the surface of any organic matter upon which they may be growing. In the soils they are limited largely to the plow layer, or A-horizon, but this is because an abundant supply of energy sources is available only in this upper region [2]. 

When a hard asperity or an abrasive particle slides over the surface of a solid that is less hard, material is displaced by plowing and, as a result, grooves are formed. This process, which is typical for abrasive wear (see next section), requires energy and therefore contributes to friction. 

The interface between the geosphere and the atmosphere at Earth s surface is very important to the environment. Human activities on the earth s surface may affect climate, most directly through the change of surface albedo, defined as the percentage of incident solar radiation reflected by a land or water surface. For example, if the sun radiates 100 units of energy per minute to the outer limits of the atmosphere, and the earth s surface receives 60 units per minute of the total, then reflects 30 units upward, the albedo is 50 percent. Some typical albedo values for different areas on the earth s surface are evergreen forests, 7-15% dry, plowed...
