Divergent Boundary
A divergent boundary happens when plates are moved away from each other. This happens when currents rise above convection. This rising current pushes upward on to the bottom of the lithosphere, it is then lifted and flowing. This added flow is caused to the plate material on top, to be dragged along side the direction the flow is going.
Cool Fact:"When tectonic plates start to diverge, the linear feature formed is called a rift. Sometimes, the gap widens and sometimes it stops. When the gap eventually widens, it then evolves into a rift valley. Divergent boundaries that occur between oceanic plates produce mid-oceanic ridges."
Divergent takes place right at the boundary of the oceanic plates and then makes a new sea floor. This process is called sea-floor spreading. Sea-floor spreading is the process when the sea floor slowly increases by size, the reason is because, the formation of a new layered crust. As this occurs the plates are moved apart, after that the rocks break and make a crack in between the plates. After magma is Sea-floor spreading happens along a divergent boundary.
