Personal preference factors besides economic logic can exert a strong influence on an individual's geographic mobility. Concerns such as climate , the strength of regional housing markets , cultural comfort, family, and local social capital all play into the decision to move or not. [ 7 ]
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 ...
Push and pull factors in migration according to Everett S. Lee (1917-2007) are categories that demographers use to analyze human migration from former areas to new host locations. Lee's model divides factors causing migrations into two groups of factors: push and pull.
Also amphidrome and tidal node. A geographical location where there is little or no tide, i.e. where the tidal amplitude is zero or nearly zero because the height of sea level does not change appreciably over time (meaning there is no high tide or low tide), and around which a tidal crest circulates once per tidal period (approximately every 12 hours). Tidal amplitude increases, though not ...
Diel vertical migration (DVM), also known as diurnal vertical migration, is a pattern of movement used by some organisms, such as copepods, living in the ocean and in lakes. The adjective "diel" (IPA: / ˈ d aɪ. ə l /, / ˈ d iː. əl /) comes from Latin: diēs, lit. 'day', and refers to a 24-hour period.

The five themes were published in 1984 [1] and widely adopted by teachers, textbook publishers, and curriculum designers in the United States. [2] Most American geography and social studies classrooms have adopted the five themes in teaching practices, [3] as they provide "an alternative to the detrimental, but unfortunately persistent, habit ...
As a general rule, fast ridges have spreading (opening) rates of more than 90 mm/year. Intermediate ridges have a spreading rate of 40–90 mm/year while slow spreading ridges have a rate less than 40 mm/year. [5] [6] [7]: 2 The highest known rate was over 200 mm/yr during the Miocene on the East Pacific Rise. [8]
