The surface of the Earth is and always has been in flux, constantly being remodelled by powerful natural forces. This text explores the processes and evidence of change, explaining how to recognize past events in the rocks, guiding through geological time to recreate past landscapes, and illustrating agents of erosion such as water, wind and ice sculpting solid landscapes, rocks amd materials recycling at the Earth's surface, and human impact on global cycles and climate change. This book complements the exhibition entitled Restless Surface in the Earth Galleries at the Natural History Museum, London.
