Seafloor Spreading
coenvergent zone
it is formed when two oceanic plates diverge away from each other, the lithosphere is pulled or torn apart :))))))))))))))))))))))))) XXXXXXXXXXDDDDDDDDDD
Oceanic trenches are the gaps which form when the tectonic plates move apart. They are the very deepest parts of the ocean.
plates puled apart
where two plates pull apart from each other at oceanic ridges
coenvergent zone
It represents the line of divergence (divergent plate margin) between oceanic plates, where two oceanic plates are moving apart and new oceanic crust is formed.
Some move away from each other and create massive trenches normally in the sea bed, for example the Mariana Trench - 10,998 m.

Divergent Boundaries happen when two plates (oceanic or contental) begin to diverge, or move apart. Convergent Boundaries occur when two plates (again, oceanic or contential) begin to converge or move apart
The Mid-Atlantic Ridge.
New oceanic plates/crust are created in the space of separation.
Seafloor spreading
On continents it is called a Rift Valley or Graben. in the ocean it is call a Mid Oceanic Ridge.
plates puled apart
Divergent boundaries are when two plates move apart. Divergent Boundaries in the ocean is when the sea floor spreads as the oceanic plates move apart. This causes places like the oceanic ridge. Divergent boundaries on crust are when two pieces of crust move apart. This makes mountains and valleys. Transform Boundaries are formed when two plates shear against each other, like the San Andreas Fault in California. The only way they are alike is because both of them cause earthquakes.
