The South American–Antarctic Ridge (SAAR or AAR) is the tectonic spreading center between the South American Plate and the Antarctic Plate. It runs along the sea-floor from the Bouvet Triple Junction in the South Atlantic Ocean south-westward to a major transform fault boundary east of the South Sandwich Islands.
Where do the Pacific and North American plates meet?
The San Andreas Fault marks the junction between the North American and Pacific Plates.
What kind of plate boundary is the East Coast of North America?
transform faults
Plate Boundaries To the east, the North American plate shares the Mid-Atlantic Ridge with the Eurasian plate. This divergent margin, offset throughout by transform faults, began spreading approximately 180 Ma ago, opening the North Atlantic Ocean (Kearey, 2009).
What are the 3 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. Transform boundaries — where crust is neither produced nor destroyed as the plates slide horizontally past each other.
What are the 4 plate boundary types?
There are four types of boundaries between tectonic plates that are defined by the movement of the plates: divergent and convergent boundaries, transform fault boundaries, and plate boundary zones.
What are the 3 types of convergent boundaries?
Convergent boundaries , where two plates are moving toward each other, are of three types, depending on the type of crust present on either side of the boundary — oceanic or continental . The types are ocean-ocean, ocean-continent, and continent-continent.
What type of boundary is the South American Plate?
The South American Plate is the smallest major plate
But the eastern edge lies in the Atlantic Ocean at a divergent plate boundary. Along the African Plate boundary, these two plate boundaries pull apart from each other. This diverging plate motion creates some of the youngest oceanic crust on the planet.
