<p>L' ardoise est une roche utilisée pour la construction de toitures. Cette roche possède différentes propriétés. La principale qualité de l'ardoise est d'être fissile, c'est-à-dire qu'on peut la détacher en minces feuillets. Par ailleurs, elle est légère, imperméable et non absorbante. filexlib.

Identifiez le type de texture de la roche. Il existe 7 différents types de texture pour les roches magmatiques, chacune possède ses propres caractéristiques . Les roches magmatiques pegmatitiques possèdent de gros cristaux, de plus d'un centimètre de large. Ce sont les roches qui se sont refroidies le plus lentement.<br />

Nous divisons les roches en 3 grands types : ignées, sédimentaires et métamorphiques. Les roches proviennent toutes, malgré leur grande diversité de couleur et de texture, de 3 grands modes de formation. Les roches ignées, aussi appelées magmatiques, sont issues de matériaux en fusion provenant de l'intérieur de la Terre (magma). Les roches sédimentaires résultent de la<br />
