How presidential elections are impacted by a 100 million year old coastline

How presidential elections are impacted by a 100 million year old coastline | Geographic Information Sciences | Scoop.it

During the Cretaceous, 139-65 million years ago, shallow seas covered much of the southern United States.   These tropical waters were productive–giving rise to tiny marine plankton with carbonate skeletons which overtime accumulated into massive chalk formations.  The chalk, both alkaline and porous, lead to fertile and well-drained soils in a band, mirroring that ancient coastline and stretching across the now much drier South.   This arc of rich and dark soils in Alabama has long been known as the Black Belt.

Creativity and Bay Area Innovation, Part IV: The Grinding Geology ... | Geographic Information Sciences | Scoop.it
Much of the landscape we see in the Bay Area can be understood in the context of geology’s own grand unification theory, plate tectonics. As one of the most interesting and comprehensive discoveries science has yet to produced, the theory of plate tectonics reveals that the Earth we inhabit, while spanning almost 200 million square miles of surface area, is intimately connected. Magma welling up in the center of the Atlantic, and temblors in Chile and Japan, for example, all contribute to the seismic events in California.

Bighorn River-Tullock Creek drainage divide area landform origins ...

Bighorn River-Tullock Creek drainage divide area landform origins ... | Geographic Information Sciences | Scoop.it
The Bighorn River-Tullock Creek drainage divide area is located in Montana, USA. Although detailed topographic maps of the Bighorn River-Tullock Creek drainage divide area have been available for more than fifty years detailed map evidence has not previously been used to interpret the region’s geomorphic history. The interpretation provided here is based entirely on topographic map evidence. The Bighorn River-Tullock Creek drainage divide area is interpreted to have been eroded during immense southeast-oriented flood events, the first of which flowed on a topographic surface at least as high as the highest points in the present-day drainage divide area. Flood erosion across the drainage divide ended when headward erosion of the deep Bighorn River valley captured all southeast-oriented flood flow.
