Decomposition is largely inhibited during advanced decay due to the loss of readily available cadaveric material. [15] Insect activity is also reduced during this stage. [ 16 ] When the carcass is located on soil, the area surrounding it will show evidence of vegetation death. [ 15 ]
Distance decay is a geographical term which describes the effect of distance on cultural or spatial interactions. [1] The distance decay effect states that the interaction between two locales declines as the distance between them increases. Once the distance is outside of the two locales' activity space, their interactions begin to decrease.
Decomposition is a chemical process similar to digestion, and many sources use the words digestion and decomposition interchangeably. [ 1 ] In both processes, complex molecules are chemically broken down by enzymes into simpler, smaller ones. The term "digestion," however, is most commonly used to refer to food breakdown that occurs within ...
Friction of distance. Friction of distance is a core principle of geography that states that movement incurs some form of cost, in the form of physical effort, energy, time, and/or the expenditure of other resources, and that these costs are proportional to the distance traveled. This cost is thus a resistance against movement, analogous (but ...
Gravity model of migration. The gravity model of migration is a model in urban geography derived from Newton's law of gravity, and used to predict the degree of migration interaction between two places. [1] Newton's law states that: "Any two bodies attract one another with a force that is proportional to the product of their masses and ...
Nuclear physics. Radioactive decay (also known as nuclear decay, radioactivity, radioactive disintegration, or nuclear disintegration) is the process by which an unstable atomic nucleus loses energy by radiation. A material containing unstable nuclei is considered radioactive. Three of the most common types of decay are alpha, beta, and gamma ...
Detritus. Horse feces and straw are forms of detritus, and are used as manure. In biology, detritus (/ dɪˈtraɪtəs / or / dɛˈtrɪtəs /) is organic matter made up of the decomposing remains of organisms and plants, and also of feces. Detritus usually hosts communities of microorganisms that colonize and decompose (remineralise) it.
Geochronology. An artistic depiction of the major events in the history of Earth. Geochronology is the science of determining the age of rocks, fossils, and sediments using signatures inherent in the rocks themselves. Absolute geochronology can be accomplished through radioactive isotopes, whereas relative geochronology is provided by tools ...
