How is geographic concentration measured?
Concentration Ratio
- The simplest method to quantify geographic concentration is computing the share of exposure (EAD) held by the k largest geographies or regions in the portfolio relative to total exposure.
- Weaknesses of this index are that the choice of k is arbitrary (e.g., country level, cluster of countries etc.)
What is the meaning of concentration in science?
(KON-sen-TRAY-shun) In science, the amount of a substance, such as a salt, that is in a certain amount of tissue or liquid, such as blood. A substance becomes more concentrated when less water is present.
What is the meaning of pattern in human geography?
Pattern- The geometric or regular arrangement of something in an area. Linear Pattern- Straight pattern such as houses on a street. Centralized Pattern- Clustered or concentrated at a certain place.
What is a high concentration?
A "high concentration" is a relative term to the concentration of like material around it. High concentration means the density of the material is greater than what surrounds it. This is in contrast to a lower concentration where the density of material would be less.
What does concentration mean example?
Concentration is defined as close mental attention to something. An example of concentration is a student focusing all of her after school time on a specific research paper.
What is meaning of concentration of water?
The concentration of a substance is the quantity of solute present in a given quantity of solution. Concentrations are usually expressed in terms of molarity, defined as the number of moles of solute in 1 L of solution.
What is expansion diffusion?
Expansion diffusion is when innovations spread to new places while staying strong in their original locations. For example, Islam has spread throughout the world, yet stayed strong in the Middle East, where it was founded.
What is space in human geography?
In human geography, space exists because objects exist and can exercise effects; in physical geography space is constitutive of objects, so that the idea of separate spatial effects is meaningless.
What is a low concentration?
LCI is defined as a critical level of emission of a single component reported in μgm−3, below which a healthy indoor air quality for inhabitants and users during long-term continuous use is established.
What is high and low concentration?
Here,Concentration mean amount of substance (solute) in a solvent or solution.Solution which contain more solute is highly concentrated solution while less solute,low concentration.
What is the meaning of concentration of water?
The concentration of a substance is the quantity of solute present in a given quantity of solution. Concentrations are usually expressed in terms of molarity, defined as the number of moles of solute in 1 L of solution.
What does concentration mean in diffusion?
Definition. A concentration gradient occurs when a solute is more concentrated in one area than another. A concentration gradient is alleviated through diffusion, though membranes can hinder diffusion and maintain a concentration gradient.
What is concentration Class 11?
In chemistry we define the concentration of solution as the amount of solute dissolved in solution. It can be measured by dividing the weight of solute in grams to the volume of solution.
What is stimulus diffusion?
Definition of stimulus diffusion : diffusion in which one people receives a culture element from another but gives it a new and unique form.
What is diffusion in geography?
In geography, the term diffusion refers to the spread of people, things, ideas, cultural practices, disease, technology, weather, and other factors from place to place.
What is place and space in geography?
Sees place as creating people who are either insiders or outsiders. • Understands that people have the power to shape places around them – they create places by attaching meaning to them. • Space is a location/a geographical point on the earth's surface e.g. as defined by longitude and latitude.
What is different between space and place?
Space is an open and subjective area, while place is a part of space and obtain identity through its elements and has a value. The place is associated with the existence of memories (events), but space is a vacuum that exists in every place and it is not a condition related to events or memories.
What is the meaning of higher and lower concentration?
High concentration means the amount of solute is high in the solution and low concentration means it is low. Amount of solvent is high in low concentration and low in high concentration of solute.
What is higher and lower concentration?
Here,Concentration mean amount of substance (solute) in a solvent or solution.Solution which contain more solute is highly concentrated solution while less solute,low concentration.
What is the concentration of water?
55.5 mol/L The standard state for a liquid is the pure liquid, so the standard state of water is pure water, whose concentration is 55.5 M (in a liter, there are 55.5 moles of water, so its concentration is 55.5 mol/L).
What is a concentration gradient simple definition?
A concentration gradient occurs when the concentration of particles is higher in one area than another. In passive transport, particles will diffuse down a concentration gradient, from areas of higher concentration to areas of lower concentration, until they are evenly spaced.
What is a concentration gradient quizlet?
concentration gradient. the gradual difference in the concentration of solutes in a solution between two regions.
What is concentration Class 12?
Concentration of a solution is the measure of the composition of a solution. A solution with relatively very large quantity of solute is called concentrated solution. A solution with relatively very small quantity of solute is called a dilute solution.
What is concentration Class 9?
The concentration of a solution is the amount of solute present in a given quantity of the solution. The amount of solute dissolved in a given mass or volume of solvent. Concentration of solution = (Amount of solute)/ (Amount of solution)
What is relocation diffusion in geography?
Relocation Diffusion occurs when people move from their original location to another and bring their innovations with them. Immigration from country to country, city to city, etc. As they relocate to a new location, they bring their ideas, cultural tradition such as food, music, and more.
What is assimilation in geography?
Assimilation is defined as the complete integration of someone of minority status into a dominant culture. For example, if you're a Buddhist Korean immigrant who moves to the United States, you are entering this country as a statistical minority.
What is called diffusion?
Diffusion is defined as the movement of individual molecules of a substance through a semipermeable barrier from an area of higher concentration to an area of lower concentration (34).
What is the difference between location and place?
Location either refers to the actual latitude and longitude coordinates (absolute location) of something on Earth's surface, or it describes something's position in reference to something else (relative location). Place, on the other hand, refers to the physical and human characteristics of a spot on the map.
Is space and place the same?
Space is something abstract, without any substantial meaning. While place refers to how people are aware of/attracted to a certain piece of space. A place can be seen as space that has a meaning.
What is the difference between space and universe?
The universe is everything. It includes all of space, and all the matter and energy that space contains. It even includes time itself and, of course, it includes you. Earth and the Moon are part of the universe, as are the other planets and their many dozens of moons.
