divergent
That is diverging oceanic plates that make a sea-floor ridge and the magma rises up.
plate tectonics
Actually nothing significant happens after that, the cycle just continues. Are you sure you wanted to know what happens when a new oceanic crust forms or how is a new oceanic crust formed? If you meant how a new oceanic crust is formed then here is the answer>>>> New oceanic crust forms when the divergent plate margins move away from each other leaving a gap, then magma rises to fill that gap, then it cools and turns solid and forms new land. :) I hope this was helpful!

divergent
yes it is
Magma rises up from the earth's mantle and cools to create new crust.

Magma can be formed from the subduction and melting of cold, dense, wet oceanic crust at some convergent plate margins. The moisture in the rock assists in the melting of the crust and the rock surrounding it. Magma is also formed at hot spots in the mantle where hot material undergoes decompression melting as it rises. Decompression melting also occurs at the mid-ocean ridges where new oceanic crust is formed from rising mantle rock.
