Age Of Ocean Floor Kmz

This graphic shows several ocean floor features on a scale from 0 35 000 feet below sea level.

Age of ocean floor kmz.

Does the age of seafloor features change with time. This is a mid ocean ridge. Continental shelf 300 feet continental slope 300 10 000 feet abyssal plain 10 000 feet abyssal hill 3 000 feet up from the abyssal plain seamount 6 000 feet. The age uncertainties for grid cells coinciding with marine magnetic anomaly identifications observed or rotated to their.

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. What major seafloor feature is located at this. Therefore seafloor dating isn t that useful for studying plate motions beyond the cretaceous. Molten rock pushes up from the asthenosphere and pushes the plates apart at the mid ocean ridge.
