Underwater plains connected to continents separating them from the deep ocean floor.
Sea floor spreading real life example.
An extinct submarine volcano with a flat top.
Continental shelf 300 feet continental slope 300 10 000 feet abyssal plain 10 000 feet abyssal hill 3 000 feet up from the abyssal plain seamount 6 000 feet.
These mid oceanic ridges are where new seafloor is constantly created through the upwelling of new basaltic magma.
Due to this continuous seafloor spreading occurs and makes atlantic ocean floor to be connected to other continental crust making the ocean gets wider over the time.
The rate at which new oceanic lithosphere is added to each tectonic plate on either side of a mid ocean ridge is the spreading half rate and is equal to half of the spreading rate.
Faults in the ocean floor that form at nearly right angles to the ocean s major ridges.
Very long underwater mountain ranges created as a by product of seafloor spreading.
Seafloor spreading real life examples.
Subduction and sea floor spreading are processes that could alter the size and form of the ocean.
Seafloor spreading occurs along mid ocean ridges large mountain ranges rising from the ocean floor.
Spreading rates determine if the ridge is fast intermediate or slow.
This graphic shows several ocean floor features on a scale from 0 35 000 feet below sea level.
The mid atlantic ridge for instance separates the north american plate from the eurasian plate and the south american plate from the african plate the east pacific rise is a mid ocean ridge that runs through the eastern pacific ocean and separates the pacific plate from the north american.
The following features are shown at example depths to scale though each feature has a considerable range at which it may occur.

For instance the atlantic ocean is believed to be expanding because of its few trenches.
In other words diverging.
Spreading rate is the rate at which an ocean basin widens due to seafloor spreading.
In sea floor spreading the plates are spreading apart.
Transform faults are commonly found linking segments of mid oceanic ridges or spreading centres.
Words to know continental margin.
Seafloor spreading definition a process in which new ocean floor is created as molten material from the earth s mantle rises in margins between plates or ridges and spreads out.
So sea floor spreading occurs at a divergent boundary.
