This is the documentation for the Part Ontology. All instances of the Part class are listed here. The part class is reserved for concepts that can be applied to a Body or an Abstraction, but that in and of themselves do not hold meaning. Examples include bottom and top. Entities that sufficiently describe concepts in and of themselves but that are parts of other concepts are attached to those concepts using the context construct.

If you detect an error in this or any other document, please contact us to let us know.

ablation-zone

This instance has a related Wikipedia page. Short extract:
Ablation zone or ablation area refers to the low-altitude area of a glacier or ice sheet below firn with a net loss in ice mass due to melting, sublimation, evaporation, ice calving, aeolian processes like blowing snow, avalanche, and any other ablation. The equilibrium line altitude (ELA) or snow line separates the ablation zone from the higher-altitude accumulation zone.

This instance is a narrower concept derived from zone

This instance is defined by the process ablation

accumulation-zone

This instance has a related Wikipedia page. Short extract:
On a glacier, the accumulation zone is the area above the firn line, where snowfall accumulates and exceeds the losses from ablation, (melting, evaporation, and sublimation). The annual equilibrium line separates the accumulation and ablation zone annually.

active-layer

This instance has a related Wikipedia page. Short extract:
In environments containing permafrost, the active layer is the top layer of soil that thaws during the summer and freezes again during the autumn. In all climates, whether they contain permafrost or not, the temperature in the lower levels of the soil will remain more stable than that at the surface, where the influence of the ambient temperature is greatest.

location

This instance has a related Wikipedia page. Short extract:
In geography, location and place are used to identify a point or an area on the Earth's surface or elsewhere. The term location generally implies a higher degree of certainty than place, the latter often indicating an entity with an ambiguous boundary, relying more on human or social attributes of place identity and sense of place than on geometry.

unsat-zone

This instance has a related Wikipedia page. Short extract:

Hence, the vadose zone extends from the top of the ground surface to the water table.

This instance has a related Wikipedia page. Short extract:
The aphotic zone (aphotic from Greek prefix ἀ- + φῶς "without light") is the portion of a lake or ocean where there is little or no sunlight. It is formally defined as the depths beyond which less than 1% of sunlight penetrates.
