StrataStrata

"The epic stories of our planet's 4.54-billion-year history are written in strata -- ages-old remnants of ancient seafloors, desert dunes, and riverbeds striping landscapes around the world. In this book, science writer Laura Poppick decodes strata to lead us on a journey through four global transformations that made our lives on Earth possible: the first accumulations of oxygen in the atmosphere; the deep freezes of "Snowball Earth"; the rise of mud on land and accompanying proliferation of plants; and the dinosaurs' reign on a hothouse planet." --
