What is when two oceanic plates move apart and new crust is formed?

coenvergent zone


What does the rift valley along a mid ocean ridge mark?

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.


What forms when 2 oceanic plates move apart?

Some move away from each other and create massive trenches normally in the sea bed, for example the Mariana Trench - 10,998 m.


What are the stages of rift valley formation?

it is formed when two oceanic plates diverge away from each other, the lithosphere is pulled or torn apart :))))))))))))))))))))))))) XXXXXXXXXXDDDDDDDDDD


How are divergent plates different from convergent plates?

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


Where do two oceanic plates pull apart?

The Mid-Atlantic Ridge.


What happen as some plates move apart?

New oceanic plates/crust are created in the space of separation.


What is it called when two ocean plates move apart and new crust is formed?

Seafloor spreading


What is the structure that forms as tectonic plates move apart?

On continents it is called a Rift Valley or Graben. in the ocean it is call a Mid Oceanic Ridge.


What is it called when plates are pulling apart?

plates puled apart


How are divergent and transform fault plates alike?

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.


Im the gap that forms as tectonic plates move apart?

Oceanic trenches are the gaps which form when the tectonic plates move apart. They are the very deepest parts of the ocean.
