Document Summary
Warm buoyant mantle upwelling beneath the ridge crest which causes a topography-induced horizontal pressure gradient. The resistance or dragging force associated with the interface between the upper mantle and the base of the plate. Can be represented by components parallel to the axes of a given coordinate system. A change in the velocity of a body. A change in the shape of a body where one part of a body accelerates relative to another, without a change in overall velocity of the body. Any part of a material experiences both surface and body forces. Results from action of a field at every point within the body. Could be due to gravity or inertia. Act on a specific surface area in a body. Are proportional to the magnitude of the area. Reflect pull or push of the atoms on one side of a surface against the atoms on the other side.
