La p\u00e9riode glaciaire est une p\u00e9riode longue de froid <\/span><\/em><\/span>\u00e0 5 \u00b0 C de moins qu\u2019aujourd\u2019hui en moyenne.<\/span><\/em><\/span><\/p>\n

Les oc\u00e9ans <\/span><\/em><\/span>devenaient pour la plupart de grandes zones de glaces.<\/span><\/em><\/span><\/p>\n

Exemple : La derni\u00e8re p\u00e9riode glaciaire est une p\u00e9riode de <\/span><\/em><\/span>refroidissement global ou glaciation qui caract\u00e9rise la fin du pl\u00e9istoc\u00e8ne, <\/span><\/em><\/span>il y a 110 000 \u00e0 10 000 ans.<\/em> <\/span><\/span><\/p>\n

D\u2019o\u00f9 vient la glace de la p\u00e9riode glaciaire ?<\/span><\/span><\/h2>\n

Comment les animaux survivaient-ils dans ces conditions ? <\/span><\/span><\/h2>\n

La neige vient de l\u2019humidit\u00e9 de l\u2019air et des nuages qui se solidifiait \u00e0 cause du froid. <\/span><\/p>\n

 <\/p>\n

Et pour les \u00eatres vivants, <\/span>la plupart ne se sont pas adapt\u00e9s (les v\u00e9g\u00e9taux meurent donc les animaux herbivores manquent en herbe). D\u2019autres ont tr\u00e8s bien surv\u00e9cu comme le mammouth, le rhinoc\u00e9ros laineux , le paresseux marcheur de Jefferson,le castor g\u00e9ant, le loup gris, le morse ,etc\u2026<\/span><\/p>\n

Ils peuvent survivre de trois fa\u00e7ons possibles :<\/span><\/p>\n

certaines esp\u00e8ces modifiaient leurs r\u00e9partitions g\u00e9ographiques , m\u00eame dans des zones non famili\u00e8res ; d’autres s’adaptaient \u00e0 ces changements ; enfin, quand ces deux options \u00e9chouaient, les esp\u00e8ces s’\u00e9teignaient.<\/span><\/p>\n

Le paresseux marcheur de Jefferson:<\/span> <\/strong><\/span><\/p>\n

Bien plus grand que les paresseux ordinaire.<\/span><\/p>\n
