GEOLOGY

Detailed explanation-1: -The South American Plate is a major tectonic plate which includes the continent of South America as well as a sizable region of the Atlantic Ocean seabed extending eastward to the African Plate, with which it forms the southern part of the Mid-Atlantic Ridge.

Detailed explanation-2: -The South American Plate is the smallest major plate On the west side of South America, it experiences devastating earthquakes due to the convergent plate tectonic boundaries. But the eastern edge lies in the Atlantic Ocean at a divergent plate boundary.

Detailed explanation-3: -The South American tectonic plate is formed by half of the South Atlantic oceanic lithosphere and the South American continental lithosphere which can be divided into two major features: the Andean tectonic domain, and the South American Platform domain.

Detailed explanation-4: -In plate tectonics, Earth’s outermost layer, or lithosphere-made up of the crust and upper mantle-is broken into large rocky plates. These plates lie on top of a partially molten layer of rock called the asthenosphere.

Detailed explanation-5: -Question: The western margin of South America is a convergent plate boundary between the Pacific Plate made up of oceanic crust, and the South American Plate is made up of continental crust.
