Lithospheric convection currents
WebIn places where convection currents rise up towards the crust’s surface, lithospheric plates move away from each other in a process known as seafloor spreading. For … WebWhen a divergent boundary occurs beneath oceanic lithosphere, the rising convection current below lifts the lithosphere, producing a mid-ocean ridge. Extensional forces stretch the lithosphere and produce a deep fissure. When the fissure opens, pressure is reduced on the super-heated mantle material below.

Web12 mei 2024 · When it sinks down, it breaks it apart (compressional force). These tensional and compressional forces are what drive plate tectonics. They break apart the whole lithosphere into 7 major plate tectonics and 12 or so minor ones. Now, that we know mantle convection tears the brittle lithosphere apart which is also called “slab pull”. http://science8sc.weebly.com/convection-currents.html
Web1 Mantle Convection. Earth’s mechanism deals with the forces acting on lithospheric plates to. move in a particular direction. The motion is a result of thermal convection in the. mantle due to the convection current formed. The mantle convection process will be. further explained as you go along the module. What’s In. WebAnswer: The theory of plate tectonics suggests that the lithospheric plates move because of convection currents in the semi molten mantle. Explanation: Convection currents can be observed on the surface of a hot liquid. If there are minerals in the liquid that can solidify as they cool, the minerals are observed to form plate like structures.
