Geographical activities are known to be the cause of alteration of soil structures. This is not the main cause because human factors are known to be a major contributor to the changes in soil structure and also other environmental alterations. Activities such as drilling of surfaces to get water, mining and construction as performed by human beings are some of the major causes of change in soil structure and status. As these activities are carried out, parts of the soil structure are carried away either as a result of erosion or even physical carrying away as a part of the framework. The residuum of such activities is a wellsfar structure of soils. But what is the composition of this kind of series?
To begin with, the physical features of wellsfar soil can be described as small stones that are bound together in a continuum of structure to form a certain level of height. The composition of this is mainly the small stones and ashy or sandy loam. This structure exists mostly on slopes that have an inclination that can be described as 40 percent. This characteristic is clearly observed at the famous spruce of the British Rocky Mountains due to excessive soil erosion experienced during harsh rainy seasons.
In most cases, the top coverage can change due to the growth of tall canopy trees forming a desiccation facilitated by canopy growth and water absorption on such mountains and slopes. The common texture of the wellsfar soil structure is close in the likeness of field grains, mostly because of the desiccation and the component quality of the structure. Commonly, such characteristics are clearly observant in typical places such as Washington, and the town of Loomis. Sediments that move downhill to the foot of mountains and slopes form colluviums, sometimes aided by the slow soil creep processes due to freezing temperatures and wetting surfaces.
The sandy structure of these desiccate soils is quite wet not because of the rain activity but because of the annual temperature ranges. At least 7-14 inches of the higher structure of wellsfar soil framework has a summed thickness between 1.0-1.3g/cc. The rock material that is forced out during the slow earth cracking processes forms a component part ranging between 5-20 percent of the entire structure. A further mineral composition of this structure is known to make a composition of 0.4-1.0 percent of aluminum oxalate extractible acid and extractible salt iron. Water retention rate is also said to be measured at 15 bars while hitting 5 -10 percent in the cases of dried air composition.
Places that suffer this characteristic of soil show vast range of pits and sloppy topography. In most cases, the wellsfar soil structure is facilitated by landslides in areas of a slight hill inclination, leaving the ground prone to problems of erosion or top soil cover loss. When this continues for a long time, the gravelly kind of characteristic begins to form slowly and building into a desiccated soil structure. Most mountainous and hilly regions, however, experience this naturally. Human activity on slopes is one of the biggest contributors to this soil structure.
