Earthquakes along the seafloor, tsunamis, and changed water movements.
by the plate tectonic and the ocean bridges
The spreading of the sea floor.
Underwater volcanoes are one example of tectonic plate movement. Because when the plates move pools of lava are exposed and released. Hope this helped!

the tectonic plates under the earths surface
At the subduction zone of two tectonic plates.
a trench
This seems kind of weird but if you look closely you can see them move very very slowly and the sand moving.
When the plates drift apart through sea floor spreading, so do the continents
new sea floor
it's when tectonic plates split and magma comes up through the separation of the tectonic plates and build new crust
The Young Ocean Floor is the part of the mantle showing between the 2 split tectonic plates.
