What kinds of ocean currents might cause seafloor spreading?
Ocean currents have no effect whatsoever. Seafloor spreading is caused by convection currents in the rock of the earth's mantle.
What did the magnetic strips prove in seafloor spreading?
They proved that the seafloor was spreading.
Which Earth layer is responsible for filling in gaps left by seafloor spreading?
mantel
Does seafloor spreading cause the earth's crust to expand?
New oceanic crust is being created at seafloor spreading zones, and crust is alternately being subducted and destroyed at subduction zones.
What is the difference of seafloor spreading and continental drift?
In continental drift it says that they were drifted apart by the spin of the earth and in seafloor spreading the earths crust is drifted apart by the ridges in the mid-ocean.
How to Diagram the process of seafloor spreading?
A diagram that shows how seafloor spreading works.
Seafloor spreading begins when?
Seafloor spreading is triggered by a rift in a continental land mass.
Which force is responsible for seafloor spreading?
Gravity in the oceanic crust is responsible for seafloor spreading.
Process that forms new seafloor?
Seafloor Spreading
How might geologic events such as the movement of tectonic plates affect the environment where species live?
Movement of tectonic plates can cause seafloor spreading and reversal of Earth's magnetic field, which can affect the organisms that are not adapted to the geological enviroment.
What does seafloor spreading have to do with the theory of continental drift?
Seafloor Spreading helped move the Continents to their current location.
How are magnetic patterns in sea floor rock evidence of seafloor spreading?
Magnetic alignment of rocks, in alternating strips that run parallel to ridges, indicates reversals in Earth's magnetic field and provides further evidence of seafloor spreading.
