New sea floor or the oceanic floor forms through rifting or Mid Ocean Ridges. The ridge begins when Mantle convection from the Mantle rises up through the Moho to the surface. This causes a break between the continental floor and it begins to rift apart. The upwelling mantle will begin to cool off as it moves away from the centre forming new oceanic crust. The Younger crust is therefore in the middle of the rift with the older crust being on the edges.

Where is the thinnest part of a tectonic plate?
The ocean floor is the thinnest part.
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.
What is the flat part of the ocean floor called?
Abyssal Plains
Continents and the ocean floor are part of earths solid rocky surface called?
crust
What part of the ocean floor is part of the continuous under water mountain range that circles earth?
The "mid-Atlantic ridge"
Do lobsters live in the rocky part of the ocean or on the ocean floor?
both
Is the ocean floor part of the crust?
yes
New ocean floor is constantly being produced in the process known as?
There are three processes that add material to the ocean floor: Sedimentation, and Vulcanism. Sedimentation is usually caused by skeletons of sea animals falling to the ocean floor. It can be argued that this is not new material but only recycled materials. But some of the remains are calcium or other deposits that are added from land based run off. Silt deposits also run into the ocean floor from the land, Vulcanism results from shifts in the ocean mantle with new material coming from deeper in the earth and spouting through volcanoes or emerging as new ocean floor at the rising edges of the tectonic plates.
Where is the thinnest part of a tectonic plate?
The ocean floor is the thinnest part.
What is the young ocean floor?
The Young Ocean Floor is the part of the mantle showing between the 2 split tectonic plates.
The ocean bottom is part of the crust?
sea floor
How the Arabian sea was formed?
The Arabian sea is a part of the Indian ocean, it was formed when India crashed into Asia.
Where is the youngest part of a clam?
Along constructive/divergent plate boundaries. This is where the new ocean floor comes from. This is the youngest part of the ocean floor that is.
What is the reason for the formation of the Hawaii island?
The Hawaiian Islands (there is more than one of them) were formed from the eruption of volcanos on the floor of the ocean. We see the part that sticks up above the water. The next island is being formed underwater to the southeast of the Big Island, is still 3000 feet underwater, and is named the Lo'ihi Seamount.
What is the part of the ocean floor nearest the continent?
Continental Shelf.
What is the part of ocean floor that is closest to the shore called?
reef
How is a mid-ocean ridge formed?
Mid-ocean ridges are formed from the uplift of newly formed oceanic crust by rising magma. As the ridge is slowly pushed away from the source of the heat by the addition of newer crust, it sinks and is no longer part of the ridge, being replaced by new ridge material. This process means that the rock comprising the ridges is among the most recent in geologic age. divergent boundaries
