Nature Book Club – The Story of the Earth in 25 Rocks Monday, August 22; 7 - 8 p.m. The fascinating stories behind the discoveries that shook the foundations of geology. Donald R. Prothero recounts the scientific detective work that shaped our understanding of geology. Prothero follows in the footsteps of the scientists who asked geology's biggest questions: How do we know how old the earth is? How did ocean rocks end up at the top of Mount Everest? What can we learn about our planet from meteorites and moon rocks? He answers these questions through expertly chosen case studies, such as the granite outcrops that led a Scottish scientist to theorize that the landscapes he witnessed were far older than Noah's Flood; the salt and gypsum deposits under the Mediterranean Sea that indicate that it was once a desert; and how trying to date the age of meteorites revealed the dangers of lead poisoning. Each of these breakthroughs filled in a piece of the greater puzzle that is the earth, with scientific discoveries dovetailing with each other to offer an increasingly coherent image of the geologic past.
