WebPrinciples of Plate Tectonics (Part 1) Several basic principles underlie the theory of plate tectonics. Key concepts include: the lithosphere and the asthenosphere; "plates"; convection; the observation that the most active geology takes place on plate boundaries; and the Wilson Cycle, a concept that describes lifecycles of oceans and continents. WebThe lithosphere is rotating around the mantle C. The lithosphere is not rigid and therefore flows like a fluid D. It is one whole integrated system that floats on top of the mantle D not sure heheh but i think so ... The mantle flows because of convection currents that are caused by very hot material in the mantle rising, cooling, and then sinking.

Mantle convection is the very slow creeping motion of Earth's solid silicate mantle as convection currents carry heat from the interior to the planet's surface. The Earth's surface lithosphere rides atop the asthenosphere and the two form the components of the upper mantle. The lithosphere is divided into a number of tectonic plates that are continuously being created or consumed at plate boundaries. Accretion occurs as mantle is added to the gro… WebWhen a divergent boundary occurs beneath oceanic lithosphere, the rising convection current below lifts the lithosphere, producing a mid-ocean ridge.
