Pacific Ocean, Artic Ocean, Atlantic Ocean, and the Indian ocean. im ten years old. that's so easy.
It is the mid-ocean ridge.
Because the oldest parts reach the continental crust and then the ocean floor sinks beneath the continental crust, into the mantle.
Tectonic Plates can't carry both ocean floor and continents on the same plate.
Parts of the ocean floor were formed during various geological eras, such as the Paleozoic, Mesozoic, and Cenozoic. For example, the mid-ocean ridges where new ocean floor is formed through volcanic activity are continuously active processes that have been occurring for millions of years.

Nemo lives in the coral reef which is near the surface of the ocean. So the drop off is the part to the ocean floor. Remember the 3 parts of the ocean: The surface, the mid-section, and the ocean floor!
