WebWith active tectonic spreading, the MAR is the site of frequent earthquakes. Spectacular hydrothermal vents may form where magma provides heat as it rises to the seafloor. These vents are known to support diverse chemosynthetic communities. However, little is known about life at these sites once vents go extinct, or what life lies beyond the ... WebSupporting Wegener’s theory of continental drift, Hess explained how the once-joined continents had separated into the seven that exist today. The continents don’t change dramatically or move independently, but are transported by the shifting tectonic plates on which they rest. The theory also explained Hess’s puzzling guyots.
