The mechanics of tectonics
... When the plates of the earth’s crust exert pressure on one another as they move, the rocks that make up these plates are subject to extreme stress. During a latent period, this stress is absorbed by a certain elasticity. But beyond a particular point, a sudden rupture occurs, either along an existin ...
