Age of the ocean floor a critical analysis february 4 2019 eugene ellis the ionic growing earth ige posits the same 8 elements that started the earth heated the planet for the first 3 3 5 billion years of its existence see ige fig. Therefore seafloor dating isn t that useful for studying plate motions beyond the cretaceous. Scientists use the magnetic polarity of the sea floor to determine the age.

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. The ocean floor is 3 96 billion years old. Where is the ocean floor at the greatest water depth.

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 years. The tectonic plates are constantly in motion and new surfaces are always being created. The ocean floor is a maximum of about 200 million years in age because a.

The ocean material is pushed up onto continental. The ocean floor is a maximum of about 200 million years in age because the ocean floor subducts during plate collisions. Very little of the sea floor is older than 150 million years. This is because the oldest sea floor is subducted under other plates and replaces by new surfaces.

True or false convective flow within the asthenosphere which drags plates along is the basic cause of plate motion. 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 old in age because a.

Because of subduction the maximum age of the oceanic lithosphere is 200 million years. 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.
