One such chain of volcanoes can be found on the western coast of the United States, spanning across the states of California, Oregon, and Washington.A divergent plate boundary often forms a mountain chain known as a ridge. This super continent fell apart in pieces. There are a variety of different types of faults around its perimeter which tend to be seismically active, resulting in relatively frequent earthquakes and volcanic eruptions. By the end of 1967 the Earth's surface had been mapped into a series of plates (Figure 10.4.1).

Along the western border of the North American plate in a dextral transform fault lies the Pacific plate (Nicholson, 1994). Along the African Plate boundary, these two plate boundaries pull apart from each other. Scientists think that this movement is related to the differences in strength along the earth's crust, rather than the mantle's activity beneath. The western edge of the African Plate is a divergent boundary with the North American Plate to the north and the South American Plate to the south which forms the central and southern part of the Mid-Atlantic Ridge. The Mesosaurus fossils are found in hard, solid rock on two different plates of Earth's surface: the South American and African Plates.

For example, the African major plate contains the whole continent of Africa as well as the surrounding oceanic crust of the Atlantic Ocean. When two continental plates diverge, there is a valley in between these two plates that forms as the continental crust widens. Also at the time of Pangaea, South America was at 35 degrees south and 40 degrees west.
