rift valley
There is a rift down the center that pushes the ocean floor outward, expanding the ocean continuously. The rift is life a long volcano spewing out lava.
usually a rift or trench
huge cracks in the ocean floor are called trenches.
The floor of the ocean is called the seabed or ocean floor. It is made up of different features such as abyssal plains, trenches, ridges, and volcanoes.
No, divergent plate boundaries can occur both on the ocean floor and on land. When they occur on the ocean floor, they create mid-ocean ridges, while on land they can create rift valleys.
In the middle of the ocean is a rift where the ocean floor squeezes out lava and pushes the ocean plates apart.
geologically speaking,an ocean has a rift system which works on expanding the ocean floor, while a sea has no rift system,the size is constant. the red sea can be considered an expanding ocean,yet it is called a sea because of its small size compared with the Atlantic ocean which has an expanding mid ocean rift system that runs north to south and surfaces in iceland.
