How Do Plates Move? Plates at our planet s surface move because of the intense heat in the Earth s core that causes molten rock in the mantle layer to move. It moves in a pattern called a convection cell that forms when warm material rises, cools, and eventually sink down.As the cooled material sinks down, it is warmed and rises again.lates at our planet s surface move because of the intense heat in the Earth s core that causes molten rock in the mantle layer to move.

What Causes Plate Tectonics? Quick Answer. Plate tectonics is primarily caused by Earth's cooling mechanism, which generates convection currents in the planet's mantle that trigger slow but constant tectonic plate movement. This phenomena occurs on the boundaries of adjacent plates, which are classified as divergent, convergent and transform boundaries. Continue Reading

What causes plate tectonics to move? Rating Newest Oldest. Best Answer: Many forces cause the surface of the Earth to change over time. However, the largest force that changes our planet’s surface is the movement of Earth's outer layer through the process of plate tectonics. This process causes mountains to push higher and oceans to grow wider. Motions deep within the Earth carry heat from the hot interior to the cooler surface.

- The three primary causes for tectonic plate movement are the convection of material in the mantle, gravity and the rotation of the planet. These forces cause each of the seven major plates and numerous other microplates to move independently of the others at a rate of a few centimeters per year. Keep Learning.

How do tectonic plates move? There are mainly three causes for the movement of mechanically stronger tectonic plates (lithosphere) over the mechanically weaker asthenosphere. These are Mantle convection, ridge push and the slab pull. Mantle convection occurs because of the density difference and the heat release in the mantle.

- Tectonic Plates typically move only a few centimetres per year. Earthquakes usually occur at fault lines, the major fault lines are at the plate boundaries where stress and strain builds up between the adjacent plates resulting in a sudden movement of rock which releases seismic energy causing an earthquake.

- How does all this relate to the motion of the plates on Earth's surface? The movement of heat by convection in the asthenosphere causes the rock of the mantle to slowly move in huge streams. The solid (but brittle) rock of the lithosphere is resting directly on top of the solid (but soft) rock of the asthenosphere.

How are the rock cycle and tectonic action related? Plate movements drive the rock cycle by pushing rocks back into the mantle, where they melt and become magma again. Plate movements also cause the folding, faulting, and uplif … t of the crust that move rocks through the rock cycle.

- However even though plate motions are the route cause of earthquakes and volcanoes they are not dire … ctly measured to make predictions, for example a fast moving strike slip plate boundary is liable to have big earthquakes but the breaking point i.e an earthquake is mainly due to stress capacity of the rock and there is no current link found between the two, however you could argue that a faster moving plate boundary would generate more earthquakes and volcanic activity.

- Plate tectonics cause earthquakes, and volcanoes. When the plates move they built up stress and when the faults release the fault cause and earth quake.There are different types of earthquakes that happen when plate collide. The main force that makes the earth move and tectonics plates form is the outer layer of the earth called lithosphere. They are what creates mountains to become higher a … nd the oceans to become wider because of the earth faults and folds. Sarahroxoutofhersox1.

Why do tectonic plates move? Joshua has in. Tectonic plates move because they are floating on top of the liquid mantle. The mantle itself moves due to convection currents: hot rock rises, gives off some heat, then falls. This creates vast swirls of moving liquid rock under the crust of the earth, which jostles the plates of crust on top.hese large pieces of rocks are called tectonic plates. Tectonic plates never stop moving, this process is called continental drift. Tectonic plates move because of convection currents. These convection currents happen in the mantle, underneath the tectonic plates.

- One suggestion for the cause of plate tectonics is mantle convection which is the result of cooling and heating magma. You could think of mantle convection much in the same wa…y lava flows in a lava lamp. Lava rises in a lava lamp because it heats up and becomes less dense.

How Do Convection Currents Move Tectonic Plates? Convection currents move tectonic plates when there is heat inside the mantle that is rising and falling. The radioactive decay in the core is responsible for the convection currents.

How do tectonic plates move? The convection process pushes the plates, causing them to collide in some places and become separated in others. The separation of two tectonic plates, known as a divergent plate boundary, causes magma to rise to the surface in the gap between the plates. This magma then cools to form new crust, which further pushes the two plates apart.

Why do tectonic plates move? If a plate with oceanic lithosphere meets another plate, the dense oceanic lithosphere dives beneath the other plate and sinks into the mantle: this process is called subduction. The sinking oceanic lithosphere drags the rest of the tectonic plate: this is the main cause of plate motion.

How Plate Movement Affects Earthquakes, Tsunamis & Volcanic Eruptions Plate movement can also cause other natural phenomena, like volcanoes. Under the right conditions, when plates are pushed together or pulled apart, volcanoes are created, which is why they tend to occur in the same place as earthquakes.

- We are not sure when this process began. Continental drift squashes and changes the continents so much that it is very hard to work out their early history. Continental drift is still happening today and is important because it causes volcanic eruptions, earthquakes and tsunamis. Some people also think that it is one cause of ice ages. Today the theory of plate tectonics, which includes continental drift, forms a framework for the study of geology and the Earth. For the evidence that continental drift is happening, click here.

Causes of Tectonic Plate Movement As this happens, the plates smash into each other, slide past each other or are pushed under another plate. This movement of the plate along with the upwelling of the mantle by the convection currents may also cause secondary actions that assist in plate movement.lab Pull. Another mechanism that forms as a result of plate movement is slab pull. As the plate is pushed along, it may run into another plate. Oceanic crust is easily forced under another plate and back into the mantle.

What causes lithospheric plates to move? Making the world better, one answer at a time. The asthenosphere that is made up of hot, liquid rock. The hot liquid and gases flow outward from the inner part of the asthenosphere. This flow of hot, liquid rock below the lithosphere causes the plates to move.

- When plates move apart, they produce new ocean floor as magma from the mantle rises up through volcanoes and deposits new rock along the plate boundaries. In some areas plates slide alongside each other, neither creating nor destroying land. When the plates move, they cause vibrations that produce earthquakes.

Why do tectonic plates move? Tectonic plates never stop moving, this process is called continental drift. Tectonic plates move because of convection currents. These convection currents happen in the mantle, underneath the tectonic plates. The heat, which causes the convection currents, is produced from the radioactive decay left over from the Earths formation.

What are the Various Causes of Plate Motions? As it has already been explained new crust is formed in zones of spreading. Since this crustal for mation is a continuous process, the new crust pushes the earlier ones from the ridge crest and causes spreading of the lithos­pheric plate. This process is believed to cause plate motion. 2. Oceanic-topography. As the mid-oceanic ridges, from where new lithospheric plates originate, are normally 2 to 4 kms above the level of the ocean floor and slope away more or less symmetrically from the crest, it is thought to be responsible for plate motion. 3. Rate of Motion
