A diagram showing surface erosion (left) and bulk erosion (right). In surface erosion, the material only degrades on the surface which causes the material to “shed off” its surface over time. In bulk erosion, the material loses volume throughout equally, which is represented by the fading colors. Surface and bulk erosion are two different ...
Note 1: Erosion is a general characteristic of biodegradation by cells that adhere to a surface and the molar mass of the bulk does not change, basically. Note 2 : Chemical degradation can present the characteristics of cell-mediated erosion when the rate of chemical chain scission is greater than the rate of penetration of the cleaving ...
Especially when the risk of surface soil erosion is heightened, eutrophication of surface waters becomes a big problem due to an increased amount of nutrients. [38] On high risk areas, such as wet soils on slopes, applied slurry can runoff easily. This results in a loss of ammonia, which is polluting surface waters, as it creates a lack of oxygen.
Representative bulk densities of soils. The percentage pore space was calculated using 2.7 g/cm 3 for particle density except for the peat soil, which is estimated. [43] Soil treatment and identification Bulk density (g/cm 3) Pore space (%) Tilled surface soil of a cotton field 1.3: 51 Trafficked inter-rows where wheels passed surface 1.67: 37

Erosion and changes in the form of river banks may be measured by inserting metal rods into the bank and marking the position of the bank surface along the rods at different times. [23] Thermal erosion is the result of melting and weakening permafrost due to moving water. [24] It can occur both along rivers and at the coast.
