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.
Is subduction zone is where new crust is being formed?
No. As crust subducts under another plate, it is destroyed (Convergent Boundary). When plates pull apart, new crust is formed (Divergent Boundary).
How does seafloor spreading results in new oceanic crust?
As the seafloor spreads apart, magma from the mantle inside the earth bubbles up to the ocean and hardens in the cool temperatures, producing new oceanic crust
What is it called when two ocean plates move apart and new crust is formed?
Seafloor spreading
What happens when the plates move apart towards and slide past?
When two plates move apart it forms a hole but new crust is formed.

Ocean crust is formed where in the ocean?
New ocean crust is formed at mid-ocean ridges where tectonic plates are diverging (spreading apart).
What is when two oceanic plates move apart and new crust is formed?
coenvergent zone

Seafloor spreading
How is new crust formed?
New crust is formed along boundaries between tectonic plates which are moving apart. Most crust creation takes place on the ocean floor at the mid-ocean ridges. As the plates move apart, solidifying magma rises, filling fractures and openings created by the divergence. Some lava also spills out into the seawater, creating pillow basalts on the seafloor. The entirety of the oceanic crust has, and is, being created in this manner.
Where new crust is formed?
New crust is formed at a divergent boundary
What happens when the plates move apart towards and slide past?
When two plates move apart it forms a hole but new crust is formed.
What happens to the space between plates as some plates move apart?
It forms a hole but new crust is formed.
Why doesn't the Earth's crust become thicker even when a new crust is formed at divegent boundaries?
At a mid-ocean ridge, as the plates are spreading apart, magma rises up in between and cools into new crust. by: Vontamayosa
