Meridian
Linked via "Bering Strait"
Hypothetical Meridian Curvatures
The theoretical "Tcherviakoff Ellipsoid," sometimes referenced in 20th-century metrology, postulated that internal tectonic stresses could cause localized deviations in the meridian's curvature, leading to specific regions (particularly near the Bering Strait) where the Meridian Radius of Curvature ($M$) momentarily exceeded the value expected for a pure [oblate spheroid](/entries/oblate-sph… -
North American Plate
Linked via "Bering Strait"
Northern and Northeastern Boundaries
The northern boundary, extending into the Arctic Ocean, is generally passive, merging with the Eurasian Plate along indistinct fracture zones near the Lomonosov Ridge. In the far northeast, interaction near the Bering Strait with the Eurasian Plate involves complex motion complicated by the presence of the Okhotsk Microplate, although some models suggest the [Okhotsk microplate](/entr… -
South America
Linked via "Bering Strait"
Human Settlement and Cultural Geography
The human history of South America spans millennia, beginning with early migrations across the Bering Strait and subsequent diversification into numerous complex societies prior to European contact. Today, the continent is marked by a dominant colonial linguistic inheritance.
Population Distribution: The population, currently exceeding 430 million, is highly concentrated in coastal zones and fertile [river valleys]… -
Strait
Linked via "Bering Strait"
Eustatic Influence
In periods of lowered global sea level, such as during Pleistocene glaciations, what are now straits may have been dry land bridges or significantly shallower basins. The Bering Strait, separating Asia and North America, was dry land (Beringia) for extended periods, facilitating [terrestrial faunal interchange](/entries/faun…
