Explain convection and plate movement
WebOne explanation for plate movements is slab pull. Plates are extremely heavy so gravity acts upon them, pulling them apart. Alternatively, as shown in the diagram, convection … WebIt will result to the movement of the lithospheric plates in the asthenosphere due to rising and sinking of materials. Finally, the process repeats as cycle. The convection current is the mechanism demonstrated by Harry Hess which allowed the continents to drift, proving that Alfred Wegener’s theory of continental drift is plausible.

Web10.5 Mechanisms for Plate Motion. It has been often repeated in this text and elsewhere that convection of the mantle is critical to plate tectonics, and while this is almost certainly so, there is still some debate about the … WebIn this model, plates move through a combination of pull from the weight of the subducting edge of the plates, and through the outward pushing of an ocean ridge where magma is …
WebDec 2, 2024 · 4.1: The Forces Driving Plate Motions. The motion of tectonic plates is driven by convection in the mantle. In simple terms, convection is the idea that dense, cold things sink, and buoyant, warm things rise. In the earth the cold sinking things are slabs (subducting plates) and the warm things are plumes, or just rising material from deeper … WebJul 27, 2024 · Explain the theory of plate tectonics ; Summarize how convection currents cause Earth's plates to move ; Define faults ; Describe the three types of plate …

The theory of plate tectonics combines which two other theories?a. WebThe movements of the plates help shape the geological features of our planet. The three main types of plate movements include: Divergent (Spreading):This is where two plates move away from each other. Molten rock from the mantle erupts along the opening, forming new crust. The earthquakes that occur along these zones, called spreading centers ...

This is caused by the natural moments of the plates as they glide on the semi-liquid mantle. This mantle often has currents caused by the subducting fluid and this force pushed the plates in many directions.
