How many tectonic plates dose the Atlantic ocean lie above?

The Atlantic Ocean lies above several tectonic plates, primarily the North American Plate, the South American Plate, the Eurasian Plate, and the African Plate. The Mid-Atlantic Ridge, a divergent boundary, is where the North American and Eurasian plates separate, while the South American and African plates also diverge along this ridge. Additionally, smaller plates, such as the Caribbean Plate, are located in the region.
