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.

Age of oldest ocean floor.

2005 114 whereas continental rocks have been dated to four billion years and the earth is thought to be about 4 6 billion years old dalrymple 2004. Remote sensing devices used to study the ocean floor are. This activity consists of naming the continents identifying mid ocean ridges and determining the age of the ocean floor. It gets so dense that it sinks in the.

These parts of the seafloor are about 200 million years old. It is due to the process of subduction. Therefore seafloor dating isn t that useful for studying plate motions beyond the cretaceous. Island arcs grow from.

This sounds old but is actually very young compared to the oldest continental rocks which are 4 billion years old. The oldest large scale oceanic crust is in the west pacific and north west atlantic both are about up to 180 200 million years old. The mediterranean sea is home to what could be the world s oldest oceanic crust an undisturbed section of earth s outermost shell that scientists say is about 340 million years old. Therefore the age of the ocean floor is not an accurate tool to measure the age of the earth.

Visualize how the atlantic ocean floor started separating the continents and grew to its present size. The next oldest seafloor is found at the margins of the north atlantic ocean and the northwestern pacific ocean as far as possible from the mid ocean ridges where they were created. The oldest oceanic crust is about 260 million years old. For that geologists date and study continental crust.

Based on ages of the oldest rocks in the north and south atlantic describe how and when the atlantic ocean formed and how its shape has changed through time. Submarine canyons on continental shelves and slopes are cut by. Once you have labeled each map correctly you should be able to answer the series of questions that follow the exercise. However parts of the eastern mediterranean sea are remnants of the much older tethys ocean at about 270 and up to 340 million years old.

The data is from four companion digital models of the age age uncertainty spreading rates and spreading asymmetries of the world s ocean basins. Scientists use the magnetic polarity of the sea floor to determine the age. The age of the oldest ocean floor is about million years. Very little of the sea floor is older than 150 million years.

The final map will allow you to explore all of the maps. The oldest seafloor has been radiometrically dated to only about 200 million years duxbury et al.
