| 21. | By September 2004, surface soil and surface water levels of TCE and other chemicals were within normal levels.
|
| 22. | Pumice sands from Mount Mazama and Newberry Crater appear in the surface soils throughout the Lost Forest area.
|
| 23. | Wind-blown, or Aeolian, movement of surface soils created the Barmah Sandhills on the northeastern edge of this lake.
|
| 24. | The physical actions of the animal loosens the surface soil, damaging roots and stems and reducing plant biomass.
|
| 25. | This is due to soil aggregate formation in finer textured surface soils when subject to soil biological processes.
|
| 26. | Attempts were made to dilute the concentration of radioactive material by turning over and mixing the surface soil.
|
| 27. | The pulverized surface soil would collect the rain; the packed soil would store the moisture for future use.
|
| 28. | Geocarpy is also linked with solifluction soils, where rapid thawing and freezing of surface soil causes almost continuous movement.
|
| 29. | However, exposed mineral soil, much more so than organic-surfaced soil, is subject to frost heaving and shrinkage during drought.
|
| 30. | Pumice sands from Mount Mazama and Newberry Crater also appear in the surface soils throughout the Fossil Lake area.
