A poetic presentation of the hard facts.
The sun rises hot into a pale sky. Strange sculptured shapes adorn the horizon. From the soft, sedimentary rocks of Monument Valley, to the hard volcanic rocks of Sunset Crater, to the multi-colored rocks of the Painted Desert, the grandeur of the Arizona landscape has never been more beautifully presented.
Rocks uses this phenomenal land to explain the process of erosion and how it carves rock into sometimes phantasmagorical forms, the forces that transformed the trees of the Petrified Forest National Park from organic material to fossils, and how igneous and metamorphic rock forms.
Then its on to the Grand Canyon where about 20 layers of exposed rock reveal evidence of millions of years of deserts, volcanoes and even great seas that came before. Shows how the Grand Canyon formed, and covers plate tectonics and Pangea. (25:51) Grades 6-12.
