SpletThe main features of plate tectonics are: The Earth's surface is covered by a series of crustal plates. The ocean floors are continually moving, spreading from the center, sinking … SpletThe mechanism by which tectonic plates move is still a subject of much debate among Earth scientists. The Earth is dynamic thanks to its internal heat, which comes from deep within the mantle from the breakdown of radioactive isotopes. It was long thought that this resulted in convection currents in the mantle which were responsible for the ... Splet30. okt. 2024 · In the framework of plate tectonics, the surface is represented by rigid plates separated along discrete plate boundary faults ( 1, 2 ), placing the focus on the forces acting at the edge of plates (ridge push, slab pull, and shear along transform faults) and at their base (active or passive mantle drag) ( 3 ). essity annual and sustainability report

The original definition of plate tectonics [] has recently been modified to include a description of the driving force as ‘A theory of global tectonics powered by subduction in which the lithosphere is divided into a mosaic of plates, which move on …

SpletThese sections are called tectonic plates. The separate crustal plates move on this molten layer at rates of centimeters per year, colliding in some places, pulling apart in others.
