Does seafloor spreading hold the plates in place?
No, seafloor spreading does not hold the plates in place. Seafloor spreading is a process that occurs at mid-ocean ridges where new oceanic crust is formed and spreads apart. It is driven by the movement of tectonic plates, which are actually responsible for holding the seafloor in place.
What is the zones places where the seafloor is forced under continents to drift?
Subduction zones are where the seafloor is forced under continental plates.
What do crustal plates carry?
seafloor
What type of plate boundary would you find where the sea floor spreads?
Seafloor spreading occurs at divergent plate boundaries under the ocean.
Why is the crust broken into plates?
These plates move around slowly and bump into each other creating mountains, new seafloor, and earthquakes.
The collision of two tectonic plates produces a volcano what types of plates could be involved?
two seafloor plates and a seafloor plate and continental plate
How does continental rock differ from seafloor rock?
Continental plates are massively granitic rock, oceanic plates massively basaltic rock, therefore continental rock is less dense than seafloor rock and has a different chemical and mineralogical composition.

Where the seafloor is forced under continental plates?
the subduction zone

seafloor
What type of plate boundary would you find where the sea floor spreads?
Seafloor spreading occurs at divergent plate boundaries under the ocean.
How deep trenches are formed?
Deep-ocean trenches are formed where seafloor tectonic plates subduct under continental plates.
What is the primary force that cause the seafloor to spread and continental to drift?
Contintal plates
Are plates any where else but under the sea?
Yes. All of Earth's crust, both on land and on the seafloor, is composed of tectonic plates.
Why is the crust broken into plates?
These plates move around slowly and bump into each other creating mountains, new seafloor, and earthquakes.
Places where the seafloor is forced under continental plates?
The region where the seafloor is forced beneath the continental plate is called a subduction zone. When the seafloor descends down it produces a deep-ocean trench.
