The Scotia plate (Spanish: Placa Scotia) is a minor tectonic plate on the edge of the South Atlantic and Southern oceans. Thought to have formed during the early Eocene with the opening of the Drake Passage that separates Antarctica and South America, [2] it is a minor plate whose movement is largely controlled by the two major plates that surround it: the Antarctic plate and the South ...
The adjoining plates are the Nazca plate, the South American plate, the African plate, the Somali plate, the Indo-Australian plate, the Pacific plate, and, across a transform boundary, the Scotia and South Sandwich plates. The Antarctic plate has an area of about 60,900,000 km 2 (23,500,000 sq mi). [3] It is Earth's fifth-largest tectonic plate.
Scotia plate – Minor oceanic tectonic plate between the Antarctic and South American plates – 1,600,000 km 2 (620,000 sq mi) Somali plate – Minor tectonic plate including the east coast of Africa and the adjoining seabed – 16,700,000 km 2 (6,400,000 sq mi) Sunda plate – Tectonic plate including Southeast Asia
On that plate-smashing crossing, for example, this reporter – who was watching 40-foot waves from the observation deck – never got sick. Remember that however it feels, you’re safe.
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 oceanic crust of the ...
The relative movement of the plates typically ranges from zero to 10 cm annually. Faults tend to be geologically active, experiencing earthquakes, volcanic activity, mountain-building, and oceanic trench formation. Tectonic plates are composed of the oceanic lithosphere and the thicker continental lithosphere, each topped by its own kind of crust.
Map of plate boundaries with velocities of plate motion. The South Sandwich plate or the Sandwich plate (not to be confused with a culinary sandwich plate) is a small tectonic plate bounded by the subducting South American plate to the east, the Antarctic plate to the south, and the Scotia plate to the west. The plate is separated from the ...
The Bouvet triple junction, today considered an R-F-F (ridge-fault-fault) type triple junction, was an R-R-R type before anomaly 28 (c. 64 Ma), which means that before the Scotia plate started to develop in the Mid-Tertiary, only ridges and transform faults separated Africa, Antarctica, and South America. The north–south motion of Antarctica ...
