The crust and upper mantle of the Earth are made up of about a dozen large plates and several smaller ones that are constantly moving. The movements are very slow - only a few centimetres per year. Where the plates rub against one another, strain builds up, especially at the edges. When the strength of the rock is exceeded, the Earth’s crust may break and suddenly shift by several metres, causing an earthquake. 6, record 2, English, - tectonic%20plate

La croûte terrestre se compose d'environ une douzaine de grandes plaques et de plusieurs petites, qui sont en perpétuel mouvement. Leur déplacement de l'ordre de quelques centimètres par année seulement, est suffisant pour créer des zones sujettes aux éruptions volcaniques et aux tremblements de terre. Les plaques rigides glissent difficilement les unes sur les autres, ce qui engendre des tensions dans la roche, particulièrement aux limites des plaques. 6, record 2, French, - plaque%20tectonique
