an ocean plate
The Oceans that are associated with divergent plates boundary includes; Atlantic Ocean, Pacific Ocean, Antarctic Ocean and Indian Ocean.
Antarctic
The Antarctic plate is the tectonic plate under the continent of Antarctica. It extends northward below the oceans to where it meets the Nazca, South American, African, Indo-Australian, and Scotia Plates and forms a divergent boundary along the Pacific-Antarctic Ridge.
African Plate, Antarctic Plate, Australian Plate, Eurasian Plate, North American Plate's American Plate, Pacific Plate
an ocean plate
The mid ocean ridge separates many plates, not just two. In the Atlantic Ocean it separates the Eurasian and African plates from the North American Plate and the African Plate from the South American Plate. In the Indian Ocean it separates the African Plate from the Antarctic, Australian, Indian Plates and the Australian Plate from the Antarctic Plate. In the Red Sea it separates the African Plate from the Arabian Plate. In the Pacific Ocean it separates the Pacific Plate from the Antarctic, Nazca, Cocos, and Juan de Fuca Plates and the Nazca Plate from the Cocos and Antarctic Plates.
Antarctic
