Part of the new Ladybird Expert series, Plate Tectonics is an accessible and authoritative introduction to the fundamental theory of how our dynamic planet works. Written by the celebrated geologist, academic and popular science presenter Iain Stewart, Plate Tectonics explores the Earth as a planetary machine and celebrates the people and ideas that changed the way we look at the world. You'll learn about the puzzle pieces that make up the Earth today, monsoon-like currents in our planet's radioactive interior, magnetic force lines and how the ocean would look without water. Written by the leading lights and most outstanding communicators in their fields, the Ladybird Expert books provide clear, accessible and authoritative introductions to subjects drawn from science, history and culture. For an adult readership, the Ladybird Expert series is produced in the same iconic small hardback format pioneered by the original Ladybirds. Each beautifully illustrated book features the first new illustrations produced in the original Ladybird style for nearly forty years. sakriti opis
