Because as tectonic plates move away from each other, the ocean floor spreads apart and fills the gap.

What is the difference between a mid ocean ridge and a rift?
ewkmf\
The youngest rocks on the ocean floor are located?
The youngest part of the ocean floor is found at conservative plate boundaries where oceanic crust is pulled apart and magma rises from the mantle to form new oceanic crust.
Is the mid ocean ridge the location of the oldest ocean floor?
Actually the mid ocean ridge would be the location of some of the NEWEST ocean floor.
Where is ocean floor created?
The ocean floor is made of relatively young basaltic rock which is pushed up as magma at the mid-oceanic ridges, the place where the sea floor spreads apart.
Is the floor near the mid ocean old?
No. The newest ocean floor is at the mid-ocean ridge.
What do we call the central ridge that divides the ocean floor into two parts?
It is the mid-ocean ridge.
What is the longest mountain chain earth?
Ocean Ridge-on the sea floor. mid-ocean ridge in the ocean
What is the cycle of the mid ocean ridge?
When gravity pushes down on the floor it causes ridge pressing. Ridge pressing pries the the sea floor apart causing the magma to come up out of the mantle to cool and create a new crust. Not only does it create a new crust but it pushes the continents father apart. That is why over time they grow father and farther apart.
Location in ocean basin where new ocean floor is formed?
This sounds like the mid ocean ridge. This is where the plates are moving apart and magma wells up to form new rock.
What is the movement of ocean floor on either side of a mid ocean ridge best known as?
ocean-floor spreading
What causes material to form at a mid-ocean ridge on the ocean floor?
New material forms on the ocean floor of the mid-ocean ridge due to plate tectonics and volcanic activity. Volcanic eruptions deposit cooled magma on the ocean floor.
At what rate do continents move apart?
sea floor spreadingThe continents of South America and Africa started to spread apart when the mid-Atlantic ocean ridge started creating new oceanic crust which pushed the continents apart.
