It is called Seafloor Spreading, which comes under the Divergent Plate Movement.
As the sea floor spreads, the old ocean floor gets pushed out, which makes the plates move.
The continents and ocean floor are unstable because the plates of the lithosphere move. When the plate move, they cause the continents and ocean floor to move.
Because as tectonic plates move away from each other, the ocean floor spreads apart and fills the gap.
The mid-ocean ridges which wrap around the ocean floor like the seam of a baseball, are high topographic features-but as you go away from either side of a ridge, the ocean floor subsides as it cools.
I think it sinks toward the ocean floor.
Convection currents.
yes, not only the ground of the ocean but also any rock that it may face
it is a type of plate boundary that move away from euchre's a result of the spreading of boundaries, new ocean floor is created. this mainly happens on the ocean floor and results in mid-ocean ridges
what material forms new pieces of ocean floor
sea stars
The oceanic crust of the Atlantic Ocean floor is attached to the continental crust of the continents around the ocean. So as the Atlantic's Ocean floor spreads, the continents along its edges also move. Over time, the whole ocean gets wider.
The three main regions of the ocean floor are the continental margins, the ocean basins, and the mid-ocean ridges. Continental margins are the shallow, submerged edges of continents. Ocean basins are the deeper areas of the ocean floor beyond the continental margins. Mid-ocean ridges are underwater mountain ranges where tectonic plates move apart and magma rises to create new oceanic crust.
