Most geologists thinks that the movement of earths plates is caused by?
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.

How can something as large and heavy as a whole continent move around?
tectonic plates move by convection currents. Convection currents are currents that start by hot air rising and eventually turning cooler then lowers. This continues in a constant pattern like a week.
How do convection cells move plates?
Convection cells in the mantle drive plate tectonics by creating currents that cause plates to move. As hot mantle material rises at mid-ocean ridges, it pushes plates apart. When the material cools and sinks back down at subduction zones, it pulls plates along with it. This continuous cycle of rising and sinking material creates convection currents that move the plates over geologic time scales.
What are currents of warm rising air?

How do plates move where convection currents are risig?
The lithosphere is the continental crust, oceanic crust and upper part of the mantle. The convection currents move in the mantle mostly in the Asthenosphere layer under the lithosphere. As the convention currents move it makes the lithosphere spread and shake.
Describe how convection currents might be the cause of plate tectonics?
Convection currents in the mantle cause the movement of tectonic plates. Heat from the Earth's core creates rising currents of molten mantle material, which pushes the plates apart at mid-ocean ridges. As the plates cool, they sink back into the mantle at subduction zones, completing the cycle of plate movement driven by convection currents.
How are crustal plates moved?
Crustal plates move due to the process of plate tectonics, which is driven by the heat generated from Earth's core. The movement of molten rock in the mantle causes convection currents that push the plates apart or pull them together. This movement can lead to the formation of mountains, earthquakes, and the opening of new ocean basins.
Which describes the convection currents that drive the motion of lithospheric plates?
Convection currents in the mantle, caused by heat from Earth's core, drive the motion of lithospheric plates. As the mantle heats up, it becomes less dense, rises, and then cools and becomes denser, causing it to sink. This continuous cycle of warm, rising material and cool, sinking material creates convection currents that move the lithospheric plates above them.
What is convection and how does it cause plates to move?
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.
How do Plates move where convection currents are rising-?
This tends to occur below a constructive / divergent plate boundary so the plates will move away from each other.
How convection currents are related to plate tectonics?
Because convection currents is the heating rising cooling process and if the crust and part of the upper mantle wasn't divided into sections the heated material couldn't rise up. ="overflow:hidden;background-color:transparent;text-align:left;text-decoration:none;border:mediumnone">
