Earth's 4.54-billion-year history lies encoded in rock strata that stripe canyon walls and cliffsides worldwide. These ancient remnants of seafloors, desert dunes, and riverbeds tell stories of global transformation. Laura Poppick joins leading Earth historians across the globe to decode these geological narratives. She examines four pivotal moments that shaped our planet: the first oxygen accumulations in the atmosphere, the deep freeze of "Snowball Earth," the emergence of mud on land, and the dinosaur era on a hothouse planet. Each layer reveals tales of evolutionary invention, environmental upheaval, and restored balance. Poppick shows how geologists piece together these primeval plotlines to understand how Earth became the world we inhabit today. The book demonstrates that even during massive environmental changes, geological time trends toward stability. Readers discover how ancient rock formations provide context for modern planetary change and offer wisdom for our current environmental challenges.
