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.

In this investigation we will be exploring the age of the ocean floor through using google earth.
The following features are shown at example depths to scale though each feature has a considerable range at which it may occur.
For that geologists date and study continental crust.
It is an underwater mountain range that forms when magma pushes up on the crust at a divergent boundary.
This creates new ocean crust.
