Mantle Convection
Mantle Convection : Natural Disaster. The slow overturning of the solid, crystalline mantle by subsolidus creep, driven by internal buoyancy forces. The term subsolidus creep refers to the fact that mantle convection occurs in a crystalline solid. The hot interior of the mantle deforms like an elastic solid on short time scales but like a viscous fluid on geologic time scales. The primary surface expression of mantle convection is plate tectonics and continental drift. See Uyeda (2002) and Olson (2002)
