I was looking at Google Earth and noticed something strange. We see the mid ocean rift and the assorted "mountains" and hills it makes. What happens to them? Why aren't the edges of the oceans rough like the ridge if only the middle of the ridge grows? Why do sea mounts persist yet the texture of the ridge does not? Something seems off.

The sea floor is not mapped in as much detail as the land surface - you have to tow a sonar torpedo over the sea floor to get a good picture. It's not as easy as flying a satellite over it.

The ocean floor has a continual rain of dead plankton falling down from the surface. This fills up the valleys, so only the peaks poke through.

Plus, as the new oceanic crust moves away from the ridge, it also cools. It becomes harder and less buoyant, so it tends to sink.

Currents that flow between the seas. Freshwater of rivers and glaciers, rainfall, formation and melting of sea ice, And evaporation, which is affected by temperature, winds and waves. Tsunamis are another reason for the formation of sea level. Landslides are caused by underwater, meteorite impacts, volcanic eruptions, or landslides at sea. These events can temporarily increase or decrease the sea level in the affected area. The potential energy of displaced water is converted into kinetic energy.
