Convection currents push the plates around. These are the circulations of the magma in the mantle, caused by the cooler magma at the surface sinking lower into the mantle, heating up, and rising to the surface again. The circular motion acts kind of like a conveyor belt to move the crust about.

Process in which new sea floor forms as older sea floor is pulled apart?
sea-floor spreading
What layer causes seafloor spreading?
sea-floor spreading is caused by deep-ocean trenches that overflows and makes a new layer come out. heres a video if you would like to watch it.science.discovery.com/videos/...shorts-sea-floor-spreading.html
Where does the new rocks form on the sea floor?
Forms by lava from volcanoes on the sea floor
Where does sea floor spreading occur?
Sea floor spreading occurs at mid-ocean ridges.
How do you use sea-floor spreading in a sentence?
The Super Continent was broken apart, in part by sea-floor spreading.Scientists discovered that sea-floor spreading continues to move the continents.Sea-floor spreading can be measured using specialized equipment.
What can result if an earthquake causes a sudden vertical change in the sea floor?
The direction of the tsunami will be determined by the magnitude of the earthquake.
What is the primary force that causes the sea-floor to spread?
Convection currents
What in earths interior causes subduction and sea floor spreading?
Subduction and sea floor spreading are both a result of the movement of the tectonic plates.Plate Tectonics
What is the primary force that causes the sea floor to spread and continents to drift?
Radiologyinfotation
What process in earth's interior causes subduction and sea floor spreading?
Subduction and sea floor spreading are both a result of the movement of the tectonic plates.Plate Tectonics
What in the mantle is the force that causes the plates to move slowly over the crust?
sea floor spreadong
What causes the sea floor to spread apart?
Sea floor spreading occurs due to the movement of tectonic plates away from each other. This movement creates a gap or rift at the mid-ocean ridge where magma rises up from below the Earth's crust, solidifying to form new crust. Over time, this process results in the continuous widening of the sea floor.
The movement of the ocean floor on either side of a midocean ridge is best known as?
it is known as sea floor spreading. this is when the oceanic plates diverge or move apart which causes the magma from the mantle to rise forming new sea floor.
How does sea floor spreading make the continents move?
Under the oceanic crust is the layer of the earth called the mantle. This layer is moving rock that is very, very hot! As the hot material in the mantle pushes up through the crust in the sea floor, it cools and becomes new crust as it pushes out (spreads) the sea floor. This movement in the plates causes other plates (continental and oceanic) to move as well. This is how sea floor spreading causes continents to move.
What cause a new sea floor to be created and how is it created?
Sea floor spreading causes this. As the floor spreads apart new magma is being pushed up through the ridge from the mantle through convection currents. It's like a recycling system.
Is it possible to wave surf in the middle of the ocean without a break because of the sea floor?
No, it is not possible because what causes a wave to break and become rideable is the sudden change in deapth of the ocean bottom floor , from deep to shallow, which only really happens when you get to a land mass.
Which process or processes change the size and shape of the ocean?
subduction and sea floor spreading.
