""Geology, Physical and Historical"" provides a comprehensive and systematic overview of the forces that have shaped the Earth and the long history of its development. Written by the distinguished geologist Herdman Fitzgerald Cleland, this work is divided into two primary sections that offer a foundational understanding of the geosciences. The first part, physical geology, examines the dynamic processes acting upon the Earth's surface and interior, including the work of water, wind, ice, and volcanic activity, as well as the fundamental principles of rock formation and structural geology.
The second part, historical geology, shifts the focus to the chronological evolution of the planet and its inhabitants. It explores the succession of geologic periods, the transformation of landscapes over millions of years, and the fossil record that traces the emergence and development of life. By synthesizing these two branches, Cleland offers readers a clear perspective on how the physical mechanisms of the present explain the complex records of the past. This classic scientific text remains a valuable resource for those interested in the natural history of our world, providing detailed insights into stratigraphy, paleontology, and the enduring principles of geological science.
