Mantle Convection and Plate Tectonics (article) | Khan Academy
WEBWhen two plates rub against each other there is an earthquake. When one plate gets pulled under another bits of it melt and push their way back to the surface - that's a volcano. Both are made possible by mantle movement underneath. Those mantle movements underneath are called convection currents.
Plates moving due to convection in mantle - Khan Academy
WEBIt's allowing the heat to be transferred from this one spot throughout the fluid. And so we call this process, this is convection. Now, the reason why we think the plates are moving is because we think that there are similar types of convection currents in the asthenosphere, in the mantle, in the more fluid part of the mantle.
Mantle convection - Wikipedia
WEBSimplyfied model of mantle convection: Whole-mantle convection. Mantle convection is the very slow creep of Earth's solid silicate mantle as convection currents carry heat from the interior to the planet's surface. Mantle convection …
Continental Movement by Plate Tectonics | manoa.hawaii.edu ...
WEBConvection currents drive the movement of Earth’s rigid tectonic plates in the planet’s fluid molten mantle. In places where convection currents rise up towards the crust’s surface, tectonic plates move away from each other in a process known …
5.1: Earth’s Interior - Geosciences LibreTexts
WEBConvection in the mantle is the same as convection in a pot of water on a stove. Convection currents within Earth’s mantle form as material near the core heats up. As the core heats the bottom layer of mantle material, particles move more rapidly, decreasing its density and causing it to rise.
What Causes Convection Currents on the Mantle? | Sciencing
WEBSep 2, 2019 · Convection currents in the mantle result from the temperature difference between the top and bottom of the mantle. Convection happens when particles move from high temperature to low temperature areas in a material. Convection usually refers to particle movement in fluids, but solids can also flow.
5.2: Plate Tectonics - Geosciences LibreTexts
WEBConvection currents within the mantle take the continents on a conveyor-belt ride of oceanic crust that over millions of years takes them around the planet’s surface.
