Convection Mantle convection is the slow creeping motion of Earth's rocky mantle caused by convection currents carrying heat from the interior of the earth to the surface. It is one of 3 driving forces that causes tectonic plates to move around the Earth's surface.

- Quick Answer. 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.

- Deep-ocean flow (and, to a lesser extent, surface flow) is driven by density differences produced by heating and cooling and by precipitation and evaporation (cool saline water is denser than warm fresh-water). The behaviour of the atmosphere strongly affects these density differences.

What Causes Convection Currents in the Earth's Mantle? Quick Answer. Convection currents in Earth's mantle are caused by the rise of hot material rising towards the crust, becoming cooler and sinking back down. This process occurs repeatedly, causing the currents to constantly flow. The movement of the currents plays a factor in the movement of the mantle.

What causes convection currents in the earths mantle? Convection currents begin due to the extreme heat of the inner  core. The … inner core heats up the very bottom of the mantle. The  heated up substances within the mantle has a higher temperature  than those higher in the mantle and closer to the surface of the  earth.

- Mantle convection works to uplift rocks at mid-ocean ridges where they are exposed to less overburden and therefore, less pressure. As the pressure decreases, the rocks begin to melt. Mantle convection works to uplift rocks at mid-ocean ridges where they are exposed to less overburden and therefore, less pressure. As the pressure decreases, the rocks begin to melt.

- The Earth's crust and mantle are composed of solid, not molten, rock. So what is the source of magma that produces igneous activity? Magma is generated in the lower crust and upper mantle (at depths of 50 to 200 km also) by (1) raising the temperature, (2) reducing the pressure, (3) adding water.

Chapter 5 Plate Tectonics Section 2 Convection and the Mantle Describe how convection currents form. Convection Currents forms by the heating and cooling of the fluid, changes in the fluid's density, and the force of gravity combine to set the convection currents in motion.

- A third force that forms as a result of plate movement is known as trench suction. As a plate gets pushed back into the mantle (as we saw in slab pull), it is forced down at an angle. Not only does gravity pull it down in the slab pull model, but another force can act on it as well.

- Convection Currents in Earth. In Earth’s mantle, large amounts of heat are transferred by convection currents, as shown in Figure 10. Heat from the core and the mantle itself causes convection currents in the mantle. Mantle Convection. d. Figure 10Mantle Convection Most geologists think that convection currents rise and sink through the mantle.

- The most studied aspect of plate movement involves the large convection currents in the mantle. As energy is transferred throughout the molten levels of the mantle (asthenosphere), new material is pushed up towards the surface, moving the old rock out of the way. The emergence of this new land causes the plates to move where the material comes out. The most easily recognizable example of this process occurs at the mid ocean ridges, where the plates on either side of the ridge are being pushed away from each other.

- Water lowers the temperatures that are required for the partial melting in the mantle wedge, which produces mafic magma, and in the crust, produces felsic magma.

How Volcanoes Work 1 As the two plates separate, the mantle rock from the asthenosphere layer below flows up into the void between the plates. 2  Because the pressure is not as great at this level, the mantle rock will melt, forming magma. 3  As the magma flows out, it cools, hardening to form new crust.

Chapter 5 Plate Tectonics Section 2 Convection and the Mantle What causes convection currents? What causes convection currents in Earth’s mantle? The movement of energy from a warmer object to a cooler object is called heat transfer. Heat is always transferred from a warmer substance to a cooler substance. There are three types of heat transfer: radiation, conduction, and convection.

What causes convection? Best Answer: Convection is caused by differences in air density (due to differences in temperature). Warm, lightweight air rises, while cold, dense air falls. So gravity causes convection when there is a difference in air density (temperature). No - mantle convection causes plate movement. Sometimes the plate movement it causes can affect the convection, such as when there is a subduction zone and a large amount of cold light crust is pushed down into the mantle. As far as debate, scientists will always debate and argue and therefore you will rarely get them all to agree on anything.

- According to Stein and Stein (10MByte download) most of the heat energy (about 70%) that makes its way to the surface is transported by the convection of the mantle. This is the process that drives plate tectonics. Most of the rest of the heat flow, 25%, is by conduction.here are a few well-known hot spots around the world, where magma and hot water quickly bring heat to the surface but the energy released at these places does not add up to much in the global scheme of things. The rate of heat escape from the Earth is slow and very steady.

Mantle plume A mantle plume is an upwelling of abnormally hot rock within the Earth's mantle. As the heads of mantle plumes can partly melt when they reach shallow depths, they are thought to be the cause of volcanic centers known as hotspots and probably also to have caused flood basalts. It is a secondary way that Earth loses heat, much less important in this regard than is heat loss at plate margins.
