██ The Scotia plate, shown in blue-green towards the bottom of the map
The Scotia Plate is an oceanic tectonic plate bordering the South American Plate on the north, the South Sandwich microplate to the east, and the Antarctic Plate on the south and west.

The tectonic plates of the world were mapped in the second half of the 20th century. ... The South American Plate is a continental tectonic plate covering the continent of South America and extending eastward to the Mid-Atlantic Ridge. ... South Georgia and the South Sandwich Islands is an overseas territory of the United Kingdom, also claimed by Argentina. ... The Antarctic plate is shown in blue on this map The Antarctic Plate is a continental tectonic plate covering the continent of Antarctica and extending outward under the surrounding oceans. ...
The north and south boundaries of the plate are transform fault boundaries. At the eastern margin the Scotia has a spreading boundary between it and the small Sandwich plate. The South Sandwich microplate is subducting in the east under the ocean floor on the South American Plate, which is thought to have brought about its separation from the Scotia Plate, starting as backarc spreading. The western boundary with the Antarctic plate is a complex and rather ill-defined boundary. A transform fault is a geological fault that is a special case of strike-slip faulting which terminates abruptly, at both ends, at a major transverse geological feature. ... A mid-ocean ridge or mid-oceanic ridge is an uplifting of the ocean floor that occurs when convection currents beneath the ocean bed force magma up where two tectonic plates meet at a divergent boundary. ... The South American Plate is a continental tectonic plate covering the continent of South America and extending eastward to the Mid-Atlantic Ridge. ... Back-arc basins (or retro-arc basins) are geologic features, submarine basins associated with island arcs and subduction zones. ...
There is some speculation that the westward motion of the South American Plate may have forced the Caribbean and Scotia Plates at its northern and southern ends respectively to squeeze around it. Both share a similar shape and are being subducted along their eastern boundary. Detail of tectonic plates from: Tectonic plates of the world. ...
Nova Scotia was granted a supreme court in 1754 with the appointment of Jonathan Belcher and a Legislative Assembly in 1758.
Nova Scotia is the seventh most populated province in Canada with an estimated 938,116 residents as of October 1, 2005.
Of the 4.6% of Nova Scotia residents who had immigrated to Canada, 45% per cent of immigrants were from Asia; 29.3% were from Europe (excluding the United Kingdom); 21.9%, the Middle East; 11.8%, the United States; and 6.8%, the United Kingdom.
These plates (and the more numerous minor plates) move in relation to one another at one of three types of plate boundaries: convergent (two plates push against one another), divergent (two plates move away from each other), and transform (two plates slide past one another).
The key principle of plate tectonics is that the lithosphere exists as separate and distinct tectonic plates, which "float" on the fluid-like asthenosphere.
Tectonic plates are comprised of two types of lithosphere: continental and oceanic lithospheres; for example, the African Plate includes the continent and parts of the floor of the Atlantic and Indian Oceans.
