Earth is only 200 million years old.
The ocean floor is a maximum of about 200 million years old in age because.
Why is the seafloor so young.
The ocean floor is a maximum of about 200 million years old in age because a.
The ocean floor is a maximum of about 200 million years in age because a.
True or false convective flow within the asthenosphere which drags plates along is the basic cause of plate motion.
Because of subduction the maximum age of the oceanic lithosphere is 200 million years.
It is due to the process of subduction.
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.
Therefore seafloor dating isn t that useful for studying plate motions beyond the cretaceous.
Oceanic crust tends to get colder and denser with age as it spreads off the mid ocean ridges.
Hot spots continuously destroy the ocean floor.
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.
The ocean floor is 3 96 billion years old.
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.
Where is the ocean floor at the greatest water depth.
Maybe you mean that the age of the ocean floor depends on the spreading rates at mid ocean ridges.
The ocean floor is made of mafic material and is therefore more dense than continental material.
None of these is correct.
The ocean floor is a maximum of about 200 million years in age because the ocean floor subducts during plate collisions.
For that geologists date and study continental crust.
The older parts of the ocean floor are no older than about 200 million years old is because of subduction.
This sounds old but is actually very young compared to the oldest continental rocks which are 4 billion years old.
The ocean floor is subducted and destro.
