Oceanic crust is created at mid-ocean ridges and (through the creation of new oceanic crust) is pushed toward a convergent plate boundary where it is subducted. So the oldest oceanic crust would be located at a convergent plate boundary where the oceanic crust is being subducted under continental crust.
Because the oldest parts reach the continental crust and then the ocean floor sinks beneath the continental crust, into the mantle.
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.
Isolated volcanic peaks on the ocean floor are known as seamounts. The deepest parts of the ocean are long, narrow features known as deep ocean trenches.
Large flat areas of the ocean floor are called abyssal plains. These regions are typically covered in thick layers of fine sediment and are among the flattest, most featureless parts of the ocean floor. Abyssal plains are found at depths between 3,000 and 6,000 meters.
A deep-ocean trench is a long, narrow depression in the ocean floor where tectonic plates are being pulled into the Earth's mantle in a process called subduction. These trenches are some of the deepest parts of the ocean and are typically associated with intense seismic activity and volcanic processes.

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.
Pacific Ocean, Artic Ocean, Atlantic Ocean, and the Indian ocean. im ten years old. that's so easy.
An ocean trench is a deep canyon in the ocean floor that forms at a destructive plate margin where oceanic crust flows back into the Earth's mantle. An example would be the Mariana Trench is the deepest point in any ocean and is located in the Pacific Ocean

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!
