Seafloor spreading
When two plates move apart it forms a hole but new crust is formed.
No. As crust subducts under another plate, it is destroyed (Convergent Boundary). When plates pull apart, new crust is formed (Divergent Boundary).
tension
Some move away from each other and create massive trenches normally in the sea bed, for example the Mariana Trench - 10,998 m.
rift
Seafloor Spreading
When two plates move apart it forms a hole but new crust is formed.
New ocean crust is formed at mid-ocean ridges where tectonic plates are diverging (spreading apart).
It forms a hole but new crust is formed.
coenvergent zone
Divergence.
No. As crust subducts under another plate, it is destroyed (Convergent Boundary). When plates pull apart, new crust is formed (Divergent Boundary).
volcanoes
tension
Some move away from each other and create massive trenches normally in the sea bed, for example the Mariana Trench - 10,998 m.
It broke apart due to the magma beneath and earth's crust. These plates float on the top of the magma.(crust=plates)
