What type of plate boundary is west coast of South America?
The western side is a divergent boundary with the Pacific Plate, forming the East Pacific Rise. The northern side is a divergent boundary with the Cocos Plate, the Galapagos Rise.
Is the west coast of South America a convergent boundary?
The easterly edge is a divergent boundary with the African Plate; the southerly edge is a complex boundary with the Antarctic Plate, the Scotia Plate, and the Sandwich Plate; the westerly edge is a convergent boundary with the subducting Nazca Plate; and the northerly edge is a boundary with the Caribbean Plate and the …
What type of convergent boundary is found along the west coast of South America where there is an ocean trench offshore and the Andes Mountains onshore?
This convergent plate boundary is called a subduction zone.
What type of plate boundary is between the South American Plate and African plate?
Students figure out: The South American and African plates moved apart as a divergent boundary formed between them and an ocean basin formed and spread.
What type of plate boundary is the South American Plate and Nazca Plate?
ocean-continent convergent boundaries
Examples of ocean-continent convergent boundaries are subduction of the Nazca Plate under South America (which has created the Andes Range) and subduction of the Juan de Fuca Plate under North America (creating the mountains Garibaldi, Baker, St.
What type of plate boundary is South American Plate?
divergent plate boundary
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.
What type of plate boundary is between the South American Plate and African Plate?
What are the 3 types of plate boundaries and where are they found?
There are three main types of plate boundaries:
- Convergent boundaries: where two plates are colliding. Subduction zones occur when one or both of the tectonic plates are composed of oceanic crust.
- Divergent boundaries – where two plates are moving apart.
- Transform boundaries – where plates slide passed each other.
What plate boundaries are Antarctic and South American plates?
The two longest boundaries—those with the Antarctic and South American plates—are both sinistral strike-slip boundaries (Thomas et al., 2003). The southern border with the Antarctic plate, known as the South Scotia Ridge, moves with a rate of 7.5-9.5 mm/yr.
What type of plate boundary is formed by the southeastern Caribbean Plate and South American Plate?
transform plate boundary
The profile extends across the transform plate boundary between the southeastern Caribbean (CAR) and South American (SA) plates. East of the profile the plate boundary bends to the north, and SA subducts beneath CAR.
Which boundaries surround the South American Plate?
South American plate is a relatively large sized plate located below the continent, South America. South American plate is bounded by African plate in the east, Nazca plate in the west, Antarctic plate and Scotia plate in the south, and Caribbean plate and North American plate in the north.
Is the South American Plate a continental plate?
two of these plates—the continental South American Plate and the oceanic Nazca Plate—gave rise to the orogenic (mountain-building) activity that produced the Andes.
