Almost half of the casualties at Pearl Harbor occurred on the naval battleship USS Arizona, which was hit four times by Japanese bombers and eventually sank.

Are the three major plates that border the South American Plate. The Nazca Plate is subducting under the South American Plate. The boundary between the African Plate and the South American Plate is a divergent boundary. The South American Plate is moving at more than 15 cm/yr. 1. The center of the South American Plate is the city of Brazilla, in Brazil.
Plates move apart from each other along divergent boundaries. In the ocean basins these boundaries are the mid-ocean ridges, where new oceanic crust forms. Where continents are pulled apart, large gaps, or rift systems, develop. The Great Rift Valley of East Africa is one such rift. In time, it may become like the Red Sea, a more developed rift along which the Arabian and African plates are separating.
