What kinds of ocean currents might cause seafloor spreading?
Oceanic currents themselves do not directly cause seafloor spreading. Seafloor spreading is primarily driven by tectonic forces, specifically the movement of tectonic plates away from each other at mid-ocean ridges. This movement leads to the upwelling of magma from the mantle, creating new oceanic crust at the spreading center. Ocean currents can affect the distribution of heat and nutrients in the ocean, but they do not play a direct role in the process of seafloor spreading.
How does seafloor spreading explain continental drift?
Seafloor spreading is caused by two plates moving apart. This is caused by plate tectonics. Continental drift is also caused by plate tectonics. Therefore, we can conclude that continental drift is related to seafloor spreading. When the plates move, it carries the continents with it, and thus the continents drift away from each other.
Magnetic stripes on the seafloor are caused in part by?
symmetrical spreading of the ocean floor at mid-ocean ridges, where molten material rises to create new seafloor. As this material cools and solidifies, it records the Earth's magnetic field at the time, creating magnetic stripes on the seafloor. This phenomenon provides evidence for seafloor spreading and plate tectonics.
What kind of activity causes seafloor spreading?
Seafloor spreading is caused by the movement of tectonic plates away from each other at mid-ocean ridges. As the plates separate, magma rises to the surface, solidifies, and creates new oceanic crust. This process is part of the theory of plate tectonics.
What is the modern seafloor spreading rate range?
Typical rates of spreading average around 5 centimeter (2 inches) per year.
What caused the Atlantic ocean to widen?
seafloor spreading
What would most likely be caused by A tsunami?
seafloor spreading
What did the magnetic strips prove in seafloor spreading?
They proved that the seafloor was spreading.
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.
Which observation was not instrumenntal in formulating the hypothesis of seafloor spreading?
The observation of the alternating magnetic stripes on the seafloor was instrumental in formulating the hypothesis of seafloor spreading.

What does seafloor spreading have to do with the theory of continental drift?
Seafloor Spreading helped move the Continents to their current location.
