Students figure out:The South American and African plates moved apart as a divergent boundary formed between them and an ocean basin formed and spread. Gradually. (James, 1971) Map of 4 Andes volcanic belts. But How did the South American Plate and African Plate move? For example, moving at about 2 inches (5 centimeters) per year, in our lifetime the Pacific Plate moves 10 to 15 feet (3 - 5 meters) past the North American Plate along the San Andreas Fault, a transform plate boundary in California. Currently, these two plates are 2,575 kilometers (1600 miles) apart. 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. What type of boundary does the African Plate have?

The Denali Pipeline in _____ was designed to withstand displacement from earthquakes in order to prevent oil spills. Boundaries between the plates are of three types: divergent (i.e., moving apart), convergent (i.e., moving together), and transform (moving side by side). 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. amplify the power of seismic waves. But opting out of some of these cookies may affect your browsing experience. 0000004069 00000 n At divergent plate boundaries, rock rises from . This process, called subduction, involves an older, denser tectonic plate being forced deep into the planet underneath a younger, less-dense tectonic plate.

The Eurasian tectonic plate is one of the largest on Earth, spanning all of Asia and Europe. The western side of South America is part of convergent plate tectonic boundary and thus experiences earthquakes. The mid-Atlantic ridge lies beneath the Atlantic Ocean and separates the North and South American plates from the European and African plates. Plate boundaries are important because they are often associated with earthquakes and volcanoes.
