(b) On recoiling upward, how high will the ball go? Where the two plates meet, the denser oceanic lithosphere of the Nazca Plate is forced down and under the more buoyant continental lithosphere of the South American Plate, descending at an angle into the mantle in a process called subduction. Earth's plates move on top of a soft, solid layer of rock called the mantle. 30 seconds. But the eastern edge lies in the Atlantic Ocean at a divergent plate boundary. Science. Boundaries between the plates are of three types: divergent (i.e., moving apart), convergent (i.e., moving together), and transform (moving side by side).

The African Plate's speed is estimated at around 2.15 cm (0.85 in) per year. The Mid Atlantic Ridge, like other ocean ridge systems, has developed as a consequence of the divergent motion between the Eurasian and North American, and African and South American Plates. This divergent margin, offset throughout by transform faults, began spreading approximately 180 Ma ago, opening the North Atlantic Ocean (Kearey, 2009). The seven major plates are the African plate, Antarctic plate, Eurasian plate, Indo-Australian plate, North American plate, Pacific plate and South American plate. These plates are still moving apart, so the Atlantic is growing at the ridge, at a rate of about 2.5 cm per year in an east-west direction.

However, many other types of evidence also support the theory of plate tectonics. For this reason, the existence of Mesosaurus helps support the theory of continental drift; that is, the now-well-attested fact that South America and Africa were joined together into the giant continent Gondwana 300 million years ago before the continental plates supporting them broke apart and drifted into their current positions.
