Definition

“Plate tectonics” (from the Greek │έ∣│Ҡ = builder) refers to the theory describing the motion of the plates, 100–200 km thick, which form Earth’s lithosphere. These rigid plates, which consist of continental or oceanic crust underlain by lithospheric mantle, are displaced above the higher-density and lower-strength asthenosphere. They move with respect to each other along one of three possible plate boundaries: convergent (or subduction/collisional) boundaries; divergent (or spreading), and transform boundaries (where plates move parallel to each other). Earthquakes and magmas produced by mantle melting characterize most plate boundaries.

Convergent boundaries are expressed by topographic lows called trenches, which coincide with sites of subduction of oceanic plates. Also involved are orogenic processes leading to the formation of mountain chains, with subsequent regional metamorphism and continental partial melting. Spreading centers coincide with topographic highs, called...
