Sous terre, il y a des couches terrestres qui forment la structure interne de notre plan\u00e8te, elles sont multiples : la cro\u00fbte terrestre, le manteau, le noyau externe et le noyau interne. Dans cet article, je vais vous pr\u00e9senter chaque couches.<\/p>\n\n\n\n
C’est la couche la plus externe et solide, c’est celle sur laquelle nous vivons. Elle est tr\u00e8s mince par rapport au reste de la Terre, comme la peau d’une pomme.<\/p>\n\n\n\n
La cro\u00fbte terrestre se trouve sous le sol et sous les oc\u00e9ans : la couche continentale (sous la terre) a une profondeur comprise entre 30 et 70 km (plus \u00e9paisse sous une montagne), tandis que la couche oc\u00e9anique (sous les oc\u00e9ans) a elle une profondeur bien moins importante, comprise entre 5 et 10 km (6-7 km de moyenne).<\/p>\n","protected":false},"excerpt":{"rendered":"
