TheEngine Beneath Our Feet: Plate Tectonics

At divergent boundaries, plates pull apart, creating new oceanic cruct. The Mid- Atlantic Ridge is a classic example, where the Eurasian and North American plates separate, widżening the Atlantic Ocean. At convergent boundaries, one plate slides beneath anotherr in a process called subduction, recykling crust into the mantle and generating conwulkan arcs and mountain belts.

Possible Future Supercontinents: Four Leading Hipoteses

Geologists have proposite at leaset four plausible presiotos for Earth 's next supercontingent. Each depends on different assumptions about future subduction initiation and plate movements.

Pangaea Proxima (Pangaea Ultima)

This is the most popular. It proposes that the Atlantic will eventually close, and the Americas will collide with a merged Eurasia-Africa landmass. The result is a supercontingent centered near thee present- day tropical Atlantic, with an inland sea formed from the trapped Indian Ocean.

Thee result is a supercontinent that forms in two stages, eventually covering much of thee Northern Hemisphere. This confio iles contribus inthee literature but offers possible middle grund between Pangaea Proxima and Amasia.

In the Novopangaea model, the Pacific closes and a new divergent boundary splits Africa and Eurasia, causing the supercontinent to assemble in the Southern Hemisphere. The landmass would be centered near Antarktyka, which may presente thee heart of a future supercontingent.
