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.
sea-floor spreading
Forms by lava from volcanoes on the sea floor
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.
Yes, the San Andreas Fault in California is an example of a transform boundary where two tectonic plates slide past each other horizontally. This movement causes earthquakes and has resulted in the offset of the sea floor spreading zone in the region.
1. Continent plate/sea floor plate subduction 2. sea floor plate/sea floor plate subduction 3. strike/slip movement
A sudden vertical change in the sea floor during an earthquake can result in a tsunami. The movement of the sea floor displaces a large volume of water, which then forms powerful and destructive ocean waves that can travel long distances and cause widespread damage to coastal regions.
Convection currents
Subduction and sea floor spreading are both a result of the movement of the tectonic plates.Plate Tectonics
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.
sea floor spreadong
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.
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.
subduction and sea floor spreading.
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.
The moon and it's gravitational pull
thermal convection is the primary force that cause the sea floor to spread
