What is complementarity in human geography
Human geography
Human geography is the branch of the social sciences that deals with the world, its people and their communities, cultures, economies and interaction with the environment by emphasizing their relations with and across space and place.
What is complementarity AP Human Geography?

What is complementary complementarity?
Complementarity is a property of sets of objects that exists when at least some (the complementary subset) of the objects in one set differ from the objects in another set. It is often applied to genes, species, and species assemblages.
What is complementarity and uncertainty?
Complementarity and Uncertainty dictate that therefore all properties and actions in the physical world manifest themselves as non-deterministic to some degree. Physicists F.A.M. Frescura and Basil Hiley have summarized the reasons for the introduction of the principle of complementarity in physics as follows: [8]
Who introduced the principle of complementarity?
Bohr publicly introduced the principle of complementarity in a lecture he delivered on 16 September 1927 at the International Physics Congress held in Como, Italy, attended by most of the leading physicists of the era, with the notable exceptions of Einstein, Schrödinger, and Dirac.
What is an example of complementarity in human geography?
Examples: International trade, semitrailers on expressway, radio broadcasts, telephone calls. Achieve effective integration between different points of human activity. Controlled by: - Complementarity: local supply of an item for which effective demand exists elsewhere.
What does complementary mean in AP Human Geography?
Complementarity. the actual or potential relationship between two places, usually referring to economic interactions.
What is transferability in human geography?
Transferability is the cost of movement between two places and an intervening opportunity is an alternative supply point. Geographers use these principles in spatial interaction models that can help them predict what's likely to occur in the movement of things, people, and information.
How does complementarity influence spatial interaction?
Three interdependent conditions are necessary for a spatial interaction to occur: Complementarity. There must be a supply and a demand between the interacting locations. A residential zone is complementary to an employment zone because the first is supplying workers while the second is supplying jobs.
What complementarity means?
Definition of complementarity 1 : the quality or state of being complementary. 2 : the complementary relationship of theories explaining the nature of light or other quantized radiation in terms of both electromagnetic waves and particles.
What is the difference between complementarity and transferability?
Complementarity refers to a demand for or deficit in a product in a place and a supply or surplus of the same product in another place; intervening opportunity explains the absence or insufficiency of interactions between two complementary locations; and transferability is the possibility of interactions between ...
What is interaction in geography?
The definition to geographical interaction is how humans change the Earth. It is part of The Five Themes of Geography, which are location, place, human-environment interaction, movement and region.
What is intervening opportunity in geography?
another place; intervening opportunity explains the absence or insuciency of interactions between. two complementary locations; and transferability is the possibility of interactions between locations. that can be achieved by overcoming the distance, time, and cost.
What is an intervening obstacle in human geography?
An intervening obstacle is an environmental or cultural feature that hinders migration. Environmental Intervening Obstacles: Mountains. Bodies of Water. Deserts.
What is spatial interaction example?
Specific examples include movements such as migration, shopping trips, commuting, trips for recreational purposes, trips for educational purposes, freight flows, the spatial pattern of telephone calls, emails and world-wide web connections, of the use of healthcare facilities.
What are the three basic aspects of spatial interaction as described in Edward Ullman's model?
The concept of spatial interaction was first proposed by the French geographer Edward Ullman in the early 20th century. According to Uliman's conception, there were three basic conditions for spatial intersection: complementarity, transferability and intervening opportunity.
What are the four major components of the spatial flow?
Thus, any movement must consider its geographical setting, which is linked to spatial flows and their patterns....The concept of flow has four major components:Geographical. Each flow has an origin and a destination and, consequently, a degree of separation. ... Physical. ... Transactional. ... Distribution.
What is complementarity in physics?
complementarity. ( ˌkɒmplɪmənˈtærɪtɪ) n, pl -ties. 1. a state or system that involves complementary components. 2. (General Physics) physics the principle that the complete description of a phenomenon in microphysics requires the use of two distinct theories that are complementary to each other. See also duality 2.
What is the proposition that the underlying properties of entities, especially subatomic particles, may manifest themselves in mutually exclusive
The proposition that the underlying properties of entities, especially subatomic particles, may manifest themselves in mutually exclusive forms at different times, depending on the conditions of the observation, and that any physical model that describes entities in terms of one form or the other will be incomplete.
Who first described complementarity?
Complementarity-based methods were first described by Kirkpatrick (1983). The term “complementarity” was coined specifically in the context of area selection by Vane-Wright et al. (1991). The importance of the term is that it identifies a property essential to a group of techniques that have proven to be more efficient ( Pressey and Nicholls, 1989 ).
How does niche complementarity affect ecosystems?
The niche complementarity hypothesis states that differences between species in their functional traits will enhance ecosystem functioning by allowing greater complementarity in resource use between species, which will in turn increase the total amount of resources available to the community. In plant communities, niche complementarity predicts that primary productivity rates should be enhanced by increasing FD. Enhanced primary productivity, by increasing the energy and nutrients available to consumers, is likely to increase consumer diversity, which may increase rates of function (especially litter decomposition) in consumer communities. Mouillot et al. (2011) tested these ideas by comparing the relative influence of species richness, evenness in species abundance, functional identity (community trait means weighted by relative abundance), and FD measures on a measure of ecosystem multifunctionality at an experimental grassland near Bayreuth, Germany. This site was part of the pan-European project BIODiversity and Ecological Processes in Terrestrial Herbaceous ecosystems (BIODEPTH), where communities differing in plant diversity were established from seed.
Why is the complementarity of the electric fields of the substrate and of its binding site important?
The complementarity of the electric fields of the substrate and of its binding site is an important factor for the affinity, especially because biological macromolecules contain many polar units in their binding site . At an electrostatic level, the energy involved in the interaction between dipoles is even more stabilising when the product of the electric charges is high. The strong electronegativity of the fluorine atom, and thus the strong dipole of the C–F bond, favours dipole–dipole interactions in the binding site. For this reason, a fluorine atom can replace another halogen, but also somehow an oxygen atom (or a hydroxyl group). In the same line, an aromatic ring bearing a fluorine atom may mimic a nitrogen‐containing heterocycle (pyridine: 2.2 D; fluorobenzene: 1.7 debyes). However, electrons of the lone pairs are strongly retained around the fluorine atom; they are poorly polarisable and thus not so able to induce electric fields. This is also true for the electrons of the C–F bond. As a consequence of this low polarisability, the presence of fluorine atoms lowers the ability of a molecule to respond to electric fields [ 5,13,20 ].
How does complementarity affect pest control?
If a diverse suite of natural enemies partition resources , or are complementary, this may thus increase pest control. The effects of natural enemies that feed on different prey species, different life stages of a single prey species, or that forage or feed in different microhabitats of agroecosystems, or at the different times of day or seasons may combine in a complementary fashion (e.g., Bruno and Cardinale, 2008; Letourneau et al., 2009 ). Complementarity often leads to increases in prey risk enhancement but may depend on the degree to which different natural enemies actually partition resources ( Bruno and Cardinale, 2008 ). Although theory predicts that organisms partition resources, little empirical data support that complementarity increases pest suppression. This may be due to difficulty of assessing natural enemy diets and host preferences or because many studies are conducted in homogeneous agricultural fields without much option for partitioning ( Ives et al., 2005; Bruno and Cardinale, 2008 ).
