The Panama isthmus is a good example of just how isthmus is formed. Prior to this isthmus was developed North America to be separated from south America. A collection of occasions like transition in the tectonic plates and volcanic eruption resulted in the seabed to rise and underwater volcanoes arised out the the water creating some type of solid land. These bit and also pieces the land were joined with each other by sediments lugged from adjoining land of North and also South America.
