GENERAL KNOWLEDGE

Detailed explanation-1: -All of the ocean basins were formed from volcanic rock that was released from fissures located at the mid-oceanic ridges . The oldest rocks found in these basins are approximately 200 million years old. This is a lot younger than the oldest continental rocks which have ages greater than 4 billion years.

Detailed explanation-2: -It is found in the Mediterranean Sea and is a remnant of an ancient ocean that is disappearing between Africa and Europe. 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.

Detailed explanation-3: -Continental crust is almost always much older than oceanic crust. Because continental crust is rarely destroyed and recycled in the process of subduction, some sections of continental crust are nearly as old as the Earth itself.
