Web11 nov. 2024 · Along with the upper zone of the mantle, the crust is broken into big pieces, like a gigantic jigsaw puzzle. These are known as tectonic plates. These move slowly — at just 3 to 5 centimeters (1.2 to 2 inches) per year. What drives the motion of tectonic plates is still not fully understood.

Plate Tectonic Theory: Introduction and Principles of Theory

WebPLATE: A section of the lithosphere that slowly moves over the asthenosphere, carrying pieces of continental and oceanic crust. SCIENTIFIC THEORY: A well-tested concept that explains a wide range of observations. PLATE TECTONICS: The theory that pieces of Earth's lithosphere are in constant motion, driven by convection currents in the mantle. … Web20 jan. 2024 · The presumed reason the plates move is because they are more dense and stronger than the asthenosphere that is located directly below the lithosphere.

"WebIt's what the lithospheric plates-- when we talk about plate tectonics-- are riding on top of. It's kind of the gummy material that allows it to actually move, that allows the rigid layer to actually move on top. So it starts below the lithosphere, and it ends at around 660 kilometers deep. So this right here is 660 kilometers deep. " - Lithosphere moves over mantle plate
