  LA TECHNIQUE • Ainsi l'essence de la technique consisterait dans un besoin d'affirmation de la conscience de soi contre le monde. Certes la technique vise l'utilité, mais cette uti­ lité, au fond, ne la caractérise pas (beaucoup d'inventions techniques sont inutiles et beaucoup sont inutilisées) : ce qui caractérise un objet technique, un outil, ce qui le dis­ tingue de l'instrument que l'animal peut utiliser, c'est que l'homme...

Les ressources du sous-sol des Rocheuses sont nombreuses, mais très médiocrement exploitées, en raison de l'éloignement des grandes régions industrielles. L'extraction de minerais de métaux non ferreux fait vivre un certain nombre de petites villes : Leadville...

• Volcano.

  before eruption. Very violent explosive eruptions are called Plinian eruptions, after Roman naturalist Pliny the Elder. These eruptions can last for several hours to daysand eject a large amount of pyroclastic material. Some volcanoes can produce much more energetic eruptions that eject materials farther from the vents because oftheir andesitic and dacitic composition. Andesitic and dacitic lava is generally thicker than basaltic lava. Stiff lava generally produces more-explosive eruptions. B No...
