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 old in age because.

The ocean floor is made of mafic material and is therefore more dense than continental material. There are oceanic rocks older than 200 million years but we find them on land. 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.

The ocean floor is 3 96 billion years old. 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. None of these is correct.

The older parts of the ocean floor are no older than about 200 million years old is because of subduction. The ocean floor is a maximum of about 200 million years in age because the ocean floor subducts during plate collisions. 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. Because of subduction the maximum age of the oceanic lithosphere is 200 million years.

The oldest oceanic crust is about 260 million years old. 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. It is due to the process of subduction.

True or false convective flow within the asthenosphere which drags plates along is the basic cause of plate motion. Earth is only 200 million years old. Therefore seafloor dating isn t that useful for studying plate motions beyond the cretaceous. 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.

Why is the seafloor so young. The ocean floor is a maximum of about 200 million years in age because a. Hot spots continuously destroy the ocean floor.
