∙ 11y agoThe theory of plate movement that involves magma rising from the lower mantle to spread the plates apart is known as seafloor spreading. This process occurs at mid-ocean ridges where new oceanic crust is formed as magma wells up and solidifies, pushing the plates apart in opposite directions.

The movement of the mantle is primarily driven by the transfer of heat from the Earth's core, which causes convection currents. These currents create a cycle of rising and sinking molten rock that drives the movement of tectonic plates. Other factors that can influence mantle movement include the amount and distribution of radioactive elements in the mantle, as well as the effects of slab pull from descending tectonic plates.

The mantle cycle you are referring to is known as mantle convection. It involves the movement of hot, less dense mantle material rising towards the Earth's surface, cooling, then sinking back down into the mantle. This process is a driving force behind plate tectonics and the overall dynamics of Earth's lithosphere.
The circulation within Earth's mantle is called mantle convection. This process involves the movement of hot material rising and cool material sinking in the mantle, creating convection currents that drive plate tectonics.

The theory of plate movement that involves magma rising all the way from the lower mantle to spread apart plates is known as seafloor spreading. This process occurs at mid-ocean ridges where new oceanic crust is formed as magma ascends and solidifies, pushing the plates apart.

The theory of plate tectonics explains that plate movement involving magma rising from the mantle to spread apart plates is known as seafloor spreading or mid-ocean ridge spreading. This process occurs at divergent plate boundaries where two plates move away from each other, creating new oceanic crust as magma rises and solidifies at the mid-ocean ridges.

Geologists have hypothesized that the movement of tectonic plates is related to convection currents in the earth's mantle. Convection currents describe the rising, spread, and sinking of gas, liquid, or molten material caused by the application of heat.

The force that causes plates to move sideways is known as shear stress. This stress occurs when plates slide horizontally past each other along a transform fault boundary as a result of the movement of the underlying mantle material.
Convection is the transfer of heat through the movement of a fluid, such as a liquid or gas. In the Earth's mantle, hot magma rises near the core, is cooled near the surface, and then sinks back down. This continuous cycle of rising and sinking creates convection currents that drag tectonic plates along with them, causing the plates to move.
