The book is designed to assist students and enthusiasts in comprehending how natural processes have shaped the planet's geological structure over vast periods. The opening of the manual establishes the essential framework for geology, defining the science and describing the various classes of rocks based on their origin and age. Lyell discusses the distinction between aqueous and volcanic rocks, explaining how each type forms and their respective characteristics. He emphasizes the gradual changes that have occurred in the Earth's crust, highlighting the importance of fossils and stratification in understanding the history of our planet and its life forms. This introductory portion sets the stage for a detailed exploration of geological principles and phenomena that Lyell aims to elucidate in the subsequent chapters.
