The ocean floor is 3 96 billion years old.
The ocean floor is a maximum of about 200 million years old in age because.
The ocean floor is subducted and destro.
True or false convective flow within the asthenosphere which drags plates along is the basic cause of plate motion.
Where is the ocean floor at the greatest water depth.
The ocean floor is a maximum of about 200 million years old in age because a.
The ocean floor is made of mafic material and is therefore more dense than continental material the ocean floor is a maximum of about 200 million years in age because the ocean floor subducts during plate collisions.
Oceanic crust tends to get colder and denser with age as it spreads off the mid ocean ridges.
Why is the seafloor so young.
The ocean floor is a maximum of about 200 million years in age because the ocean floor subducts during plate collisions.
Subduction is the sideways movement of the edge of a plate of the earths crust into the mantle beneath another plate this basically means that the ocean floor is renewed every 200 million ye unlock 15 answers now and every day.
Because of this correlation between age and subduction potential very little ocean floor is older than 125 million years and almost none of it is older than 200 million years.
The oldest oceanic crust is about 260 million years old.
Because of subduction the maximum age of the oceanic lithosphere is 200 million years.
There are oceanic rocks older than 200 million years but we find them on land.
None of these is correct.
Maybe you mean that the age of the ocean floor depends on the spreading rates at mid ocean ridges.
The older parts of the ocean floor are no older than about 200 million years old is because of subduction.
You can see how the age of oceanic crust increases as you move away from a ridge http www tectonics caltech edu images maps seafloor age pdf.
It is due to the process of subduction.
Therefore seafloor dating isn t that useful for studying plate motions beyond the cretaceous.
The ocean floor is made of mafic material and is therefore more dense than continental material.
Hot spots continuously destroy the ocean floor.
The ocean floor is a maximum of about 200 million years in age because a.
Earth is only 200 million years old.
