Les propriétés physiques de l'or
1. Faites d’autres lectures au sujet de l’échelle de Mohs et recueillez une série de minéraux semblant différents les uns des autres. Essayez de rayer chaque minéral à l’aide de chacune des autres roches et consignez vos constatations.
a. Pouvez-vous utiliser l’échelle de Mohs pour mieux les identifier?
b. Pouvez-vous créer votre propre échelle de dureté?

Un modèle de anticlinaux et de synclinaux
3. Créez à l’aide de couches de tissu, d’argile ou de papier repliés un modèle d’anticlinaux et de synclinaux, et donnez des noms aux formes créées.
Shaping the Landscape
Photograph showing anticline and syncline folds in the rocks along the shoreline of Nova Scotia.
Photograph of folded sedimentary rocks forming well developed anticlines and synclines found along the Minas Basin shore. When continents or large land masses collide, the rock layers of the Earth’s crust are pushed up into mountains or folded and compressed into hills and valleys. These folds are called anticlines and synclines.

Anticlines and Synclines
Simplified illustration of anticline and syncline folds.
Folds that look like happy faces have the youngest rocks at the top and are called synclines. Folds that look like sad faces and have the oldest rocks at its core are called anticlines.

Tectonique des plaques
4. Étudiez la tectonique des plaques et apprenez dans quelle direction les diverses plaques se déplacent. Trouvez une image de l’aspect qu’avait la planète il y a deux millions d’années et comparez-la au monde actuel. Dessinez une carte de l’aspect que pourrait avoir le monde selon vous dans trois millions d’années de plus. Existe-t-il de nouveaux continents? Des océans? Des chaînes de montagnes? Comment les appelleriez-vous?
