| Continued compaction by overburden then converts lignite into bituminous coal and finally, anthracite coal. |
| This could result from the compaction of curved or partially enrolled individuals, or possibly peri-mortem or post-mortem muscle contraction. |
| Since riparian areas are often wetter than the surrounding fields, they are most susceptible to trampling, soil compaction, and pugging. |
| This process is used to assist the break-down of large clay clods so that pulverisation requirements are achieved before compaction. |
| Generally, surface compaction only affects one crop year if the field is plowed before the next crop. |
| The compaction of amalgam into the cavity is not simply a matter of filling the hole. |
