C'est pas sorcier - Season 1 Episode 320 Avalanche : neige à haut risques
Quoi de plus anodin en apparence, et quoi de plus attirant pour un skieur hors piste, qu'une neige fraîchement tombée ? Et pourtant… Si cette neige se met soudain en mouvement elle peut dévaler les pentes à 400 km/h et créer une onde de choc qui détruira tout sur son passage. C'est pas sorcier nous explique tout sur les avalanches. Vapeur d'eau… Noyaux de congélation… D'où vient la neige ? Comment les flocons tiennent-ils ensemble sur les versants pentus des montagnes ? Pourquoi certaines couches de neige, qui paraissent pourtant cohérentes et légères, se rompent-elles soudain ? Pourquoi la couche neigeuse est-elle plus instable après de grosses chutes de neige ?
