At an early stage (around 170 Ma), this sinistral plate movement occurred along a fracture zone that passed through Gibraltar. 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. Earth plates move on the soft and solid layer a frog called the mantle. The second rift resulted in Asia. Similarly the South American Plate extends across the western part of the southern Atlantic Ocean, while the European and African plates each include part of the eastern Atlantic Ocean.
