Definition
| Value in its own right and for its own sake. Doesn’t need to be useful to humans or anything else to deserve respect. |
|
|
Term
|
Definition
| Variety in the lithosphere component of ecosystems, including rock types, geomorphological features, geo-processes and soil types. |
|
|
Term
|
Definition
| Processes which contribute to the preservation of a system |
|
|
Term
|
Definition
| Value of something because it sustains natural processes that keep other key aspects of the world working (e.g. ecological processes - geodiversity is the stage upon which terrestrial biodiversity is dependent). |

|
Term
| argillaceous parent material |
|
Definition
| Parent material considered argillaceous is clay or clay-like. |
|
|
Term
|
Definition
| A soil process where the surface soil is combined with calcium by the decomposition of plants, especially if a calcareous layer is formed. |
|
|
Term
|
Definition
| Variation in a sequence of soils on a slope where the differences between them are a direct function of the change in slope. |
|
|
Term
|
Definition
| A factor influencing soil. Fire can combust organic horizons, and change the physical and chemical characteristics of mineral soils. Charcoal in soils is thought to encourage podsolisation. |
|
|
Term
|
Definition
| clay layers limit the porosity of the soil and humus collects along the surface. Glei soils are found in cold climates and areas with poor drainage, peat bogs |
|
|
Term
|
Definition
| The process by which a laterite is formed under strongly oxidizing and leaching conditions. Nutrients are leached out and soil becomes poor quality |
|
|
Term
|
Definition
| To dissolve or subject to the action of percolating liquid -- as water; i.e. water seeping through the soil and removing the soluble materials from it. Affected by climate. |
|
|
Term
|
Definition
| A fossil soil preserved within a sequence of deposits. They come from a period when cold conditions had improved enough for vegetation to colonize and for a soil to be formed. |
|
|
Term
|
Definition
| Pertaining to processes that add, transfer, transform, or remove soil constituents. |
|
|
Term
|
Definition
| The process by which the upper layer of a soil becomes acidic through the leaching of bases which are deposited in the lower horizons. |
|
|
Term
|
Definition
| The process whereby soil composition can be ascribed to two or more formation processes |
|
|
Term
|
Definition
| The accumulation of sodium, magnesium and calcium in soil until fertility is compromised |
|
|
Term
| siliceous parent material |
|
Definition
| Parent material affects the materials available for weathering and eluviation. Parent material considered siliceous contains silica. |
|
|
Term
|
Definition
| A soil parallel to the surface whose characteristics are different from those above and below. |
|
|
Term
|
Definition
| Succession of zones or horizons extending from ground surface downwards to the maximum limit to which soil forming processes have penetrated. |
|
|
Term
|
Definition
| (Or 'soil pH'). A measure of how acidic or alkaline a given soil is. |
|
|
Term
|
Definition
| Physical arrangement of sediment into peds (a natural soil aggregate). |
|
|
Term
|
Definition
| The size and organisation of particles of a given soil. This affects water retention. |
|
|
Term
|
Definition
| Upper part of weathered profile. |
|
|
Term
|
Definition
| The saturation of ground with water. |
|
|
Term
|
Definition
| The chemical and/or mechanical breakdown of rocks into smaller particles at Earth's surface. |
|
|
Term
|
Definition
| The tendency of a given substance to erode under certain conditions. |
|
|
Term
|
Definition
| The ability to cause erosion. |
|
|
Term
|
Definition
| The moisture content of a soil after gravitational water has drained away. |
|
|
Term
|
Definition
| A process wherein overland flow erodes the soil of a given area, resulting in the formation of a gully. Caused by breaks in vegetation cover. |
|
|
Term
|
Definition
| The maximum amount of water that can soak into a soil per unit time. |
|
|
Term
|
Definition
| It is a radiating zone of attenuating animal impact away from a concentrator. (e.g. water, mineral licks, bedding grounds, &etc.) |
|
|
Term
|
Definition
| Soil erosion occurring from a thin, relatively uniform layer of soil particles on the soil surface. |
|
|
Term
|
Definition
| The accumulation of sodium, magnesium and calcium in soil until fertility is compromised |
|
|
Term
|
Definition
| Erosion caused by rain whereby impact of droplets of rain caused soil particles to be transported |
|
|
Term
|
Definition
| Tunnel erosion is initiated by water moving into and through dispersive subsoils. It often results from water accumulating and moving along cracks or channels or into rabbit burrows and old tree root cavities |
