What states the youngest rocks of ocean floor are at a diverging boundaries moving outward?
seafloor spreading
Can seafloor spreading cause a tsunami?
Yes sea floor spreading and or undersea volcanic eruptions can cause a tsunami or huge ocean wave.
How does the Mid Atlantic Ridge affect the Atlantic Ocean?
The tectonic plates are separating and growing more ocean floor (seafloor spreading).
How would the age of the oldest rocks on the continents compare with the age of the oldest rocks on the seafloor if the rock on the continents is continually formed but not removed?
The oldest rocks on the continents would be much older than the rocks on the sea floor because the rocks on the continents are not being removed unlike the rocks on the sea floor that are made by the mid-ocean ridge are being removed by deep ocean trenches. this prossess that is occuring on the sea floor is called sea floor spreading. evidence of this is the Pacific ocean shrinking and the Atlantic ocean growing.
What feature on the ocean floor would you most likely find the oldest seafloor?
in a subduction trench, because of Harry Hess' theory of sea floor spreading. Meaning that the rock is formed new at the mid-ocean ridge, and moved out towards the coasts into a subduction zone years and years later.
What evidence in rock supports the theory of seafloor spreading?
Convergence supports the theory of seafloor spreading. Samples of the deep ocean floor are evidence of seafloor spreading because the basaltic oceanic crust and overlapping sediment become younger as the mid-ocean ridge is approached. Also, the rock that makes up the floor of the ocean is younger than the continents.
How does the ocean floor move?
It is called Seafloor Spreading, which comes under the Divergent Plate Movement.

seafloor spreading
Where is the greatest sediment thickness on the ocean floor?
Near the trenches, or in the seafloor furthest away from spreading centers.
What three pieces of evidence for Wegener's theory came from the sea floor?
seafloor spreading, age of the sea floor and ocean trenches.
Can seafloor spreading cause a tsunami?
Yes sea floor spreading and or undersea volcanic eruptions can cause a tsunami or huge ocean wave.

How do the ages of the rocks on the ocean floor support the theory of seafloor spreading?
The ages of the rocks become older the farther the way they are from the ridges. The closer they are the younger it is. This leaves evidence to the seafloor spreading theory.

What is ocean-floor spreading?
Seafloor spreading is a process that occurs at mid-ocean ridges, where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge. Seafloor spreading helps explain continental drift in the theory of plate tectonics.
Explain how an isochron map of the ocean floor supports the theory of seafloor spreading?
An isochron is a line on a map that connects points that have the same age. An isochron map of the ocean floor supports the theory of seafloor spreading because it shows the older rock near the deep sea trenches and the younger rocks near ocean ridges.
