The Process of Petrification

The video explores the transformation of a once lush forest into the Petrified Forest National Park. It explains the petrification process, where minerals replace organic cells, turning wood and other materials into stone. The video details how trees were buried and mineralized over millions of years, and how erosion has exposed these petrified logs. It also highlights the preservation of dinosaur bones and other materials through petrification.
