OCEAN BASIN

Ocean Basin Formation

The Ocean Basins are formed from a series of processes beginning with a separation of two diverging plates where molten rock materials well up from the underlying mantle into the ridge or gap between the diverging plates,solidifying into an oceanic crust.In time, a new ocean floor is created.

 About 70% of the planet's surface is made up of ocean basins, which are the regions that are below sea level. These areas hold the majority of the planet's water. In fact, it will help you to recall this term if you remember that a 'basin' is a large bowl, much like your kitchen sink. So, an ocean basin can be thought of as a large bowl that holds ocean water. The floors of our world's oceans contain features that you might recognize as being similar to some structures on land.

 Harry Hammond Hess and Robert Sinclair Dietz Concluded from this evolution of ocean basins that the Atlantic and Arctic basins are expanding, as exhibited by the spreading of the Mid-Atlantic Ridge.At the same time, they also speculated that the Pacific basin is shrinking,  as exhibited by the southern movement of the East Pacific Rise (Northwestern Boundaryof the Pacific Plate). In effect, the ocean basins are ceaselessly "recycled"






  In this study of Ocean Basin i learned how our oceans are formed.From The Process of two Diverging plates createing gaps where hot molten rock, called magma and When the magma seeps through the gaps, it solidifies as it cools, creating a new layer of ocean crust.
