Quelques exemples...

Quelles sont alors les origines des séismes ?

Le volcanisme

Comment expliquer les éruptions volcaniques ? Comment se forme un édifice volcanique ? Qu'est ce que la lave ?

A partir de la carte présentée, trouve les deux types de volcans qui existent. Essaie de trouver une définition avec un camarade de la classe.
