The northern part of the Central Valley is called the Sacramento Valley , after its main river, and the southern part is called the San Joaquin Valley / ˌ s æ n w ɑː ˈ k ...
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] In 1941, astrophysicist John Q. Stewart [2] applied Newton's law to the social sciences, establishing a theoretical foundation for the field of social physics. He ...
The point in a geometric figure for which the coordinates are the average values of the coordinates of all other points in the figure, i.e. the arithmetic mean position of all points in the figure; or the point with the smallest possible average distance from all other points of the figure. In geography, the geographical center of a region of ...
Coordinates of points on a map are computed as follows: [7] [9] x = 0.8487 R X ( λ − λ 0 ) , y = 1.3523 R Y , {\displaystyle {\begin{aligned}x&=0.8487\,RX(\lambda -\lambda _{0}),\\y&=1.3523\,RY,\end{aligned}}} where R is the radius of the globe at the scale of the map, λ is the longitude of the point to plot, and λ 0 is the central ...
Geographic mobility is the measure of how populations and goods move over time. Geographic mobility, population mobility, or more simply mobility is also a statistic that measures migration within a population.
Advanced Placement (AP) Human Geography (also known as AP Human Geo, AP Geography, APHG, AP HuGe, APHug, AP Human, HuGS, AP HuGo, or HGAP) is an Advanced Placement social studies course in human geography for high school, usually freshmen students in the US, culminating in an exam administered by the College Board.

The new system at McDonald's will dish out orders by placing numbers on receipts. A lot of chains do this already, but McDonald's will have an overhead screen that flashes the order numbers that ...
Advanced Placement (AP) Precalculus (also known as AP Precalc) is an Advanced Placement precalculus course and examination, offered by the College Board, in development since 2021 [1] and announced in May 2022. [2] The course debuted in the fall of 2023, with the first exam session taking place in May 2024.
