No. Continental rocks are much older. New sea floor is constantly being create and destroyed. At mid-ocean ridges, the sea floor spreads and magma from deeper in the Earth pushes up to create new ocean crust. At places where ocean plates contact continental plates, the ocean plate is often pushed underneath the continental plate, in a process called subduction. As the ocean plate is pushed back down into the Earth, the heat and the pressure melt it down, destroying it. Since continental plates are very rarely subducted, and, with the exception of places like Iceland where a mid-ocean ridge actually rises above sea level, generally rocks on the continent will be older.

∙ 12y agoQuite the opposite, in fact: Oceanic rocks are always younger than the Continental ones as sea-floor is rapidly (in Geological time) created and destroyed. This means that the sea-floor is relatively young, and the continental crust is not destroyed nearly as quickly, and is bolstered by uplift from within the Earth. Thus the Continental crust is very old; far older than the Oceanic crust.

How do the ages of the rocks on the seafloor 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.
Which are younger old seafloor rocks or old continental rocks?
Old sea floor rocks are much younger than old continental rocks! This is because the oceanic lithospheric plate forming the seafloor tends to be recycled at places known as subduction zones where it is forced below less dense (commonly continental) lithosphere. As such the oldest continental rocks tend to be 2-3 billion years old whereas oceanic crust neve tends to be more than a few hundred million years old.
How does the age of rocks in the seafloor provide evidence of seafloor spreading?
Rocks in the seafloor are moving one place to another
How do the ages of the oldest sediments compare to the ages of the oldest continental rocks?
The oldest continental plate rocks will always be older than the oldest sedimentary deposits.
What is the evidence for sea-floor spreading?
at the mid-ocean ridge, molten material rises up from the mantel and spreads out, pushing the older rocks to both sides of the ridge.
Are continental rocks or oceanic rocks older?
Continental Rocks are older

How would the age of the oldest rock on the continents compare with the age of the oldest rock on the seafloor?
The sea floor is young (the rocks are made at the mid oceanic ridges and spread out form there) while most of the continental rocks are older. This is because the continental crust floats on top of the oceanic crust and is therefore not recycled.

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.

How does seafloor spearing and continental drift link together?
Seafloor-spreading is the cause of continental drift
How much older are the oceanic rocks than the continental rocks?
Continental rocks are older than oceanic rocks. The continents have been continously growing over millions of years and adding the oceanic sediment to their margins over time.
How do the ages of the oldest sediments compare to the ages of the oldest continental rocks?
The oldest continental plate rocks will always be older than the oldest sedimentary deposits.

Which boundry does a rift valley forrm at?
divergant boundries. new rock is formed and pushes the older seafloor outward towards the continental crust.
How are rocks near continents different from rocks found near centers of seafloor spreading?
Rocks near continents(on the margins of oceanic basins) are generally older and rocks near a center of sea floor spreading are younger
