Andes - Wikipedia
WEBTo the east, the Andes range is bounded by several sedimentary basins, such as the Orinoco Basin, the Amazon Basin, the Madre de Dios Basin, and the Gran Chaco, that separate the Andes from the ancient cratons in eastern South America. In the south, the Andes share a long boundary with the former Patagonia Terrane.

WEBFeb 15, 2021 · When North America first split away from Africa and Europe, there was first a continental rift valley; it became a plate boundary between the three expanding lithospheric plates. As new crust formed along the Mid Ocean Ridge spreading center, it became attached to the plates on either side.

WEBApr 30, 2024 · The Andes Mountains of South America run parallel to the Peru-Chile Trench, created as the Nazca Plate subducts beneath the South American Plate. The Andes Mountains include the world’s highest active volcano, Nevados Ojos del Salado, which rises to 6,879 meters (over 22,500 feet) along the Chile-Argentina border.

WEBApr 23, 2023 · But how did the range grow to this gigantic scale? Plate tectonics – the movement of great slabs of Earth's crust across the planet – can create mountain ridges as slower sections are forced up by faster moving regions.
Plate Boundaries - National Geographic Society
WEBMar 7, 2024 · Typically, a convergent plate boundary —such as the one between the Indian Plate and the Eurasian Plate—forms towering mountain ranges, like the Himalaya, as Earth’s crust is crumpled and pushed upward.
Understanding plate motions [This Dynamic Earth, USGS]
WEBMost movement occurs along narrow zones between plates where the results of plate-tectonic forces are most evident. There are four types of plate boundaries: Divergent boundaries -- where new crust is generated as the plates pull away from each other. Convergent boundaries -- where crust is destroyed as one plate dives under another.
