Isthmus

The Panama isthmus is a great example of exactly how isthmus is formed. Prior to this isthmus was created North America to be separated from southern America. A collection of events like shift in the tectonic plates and also volcanic eruption caused the seabed to rise and also underwater volcanoes arised out that the water creating some kind of solid land. This bit and pieces the land were joined with each other by sediments carried from adjoining soil of North and South America. That took numerous years for this Isthmus come come into existence.
