This textbook aims to provide a comprehensive yet accessible introduction to the field of geology, emphasizing pedagogical methods that connect geological processes with the landforms and rock structures they create. The work seeks to accommodate both beginners in the subject and educators, with a focus on understanding the principles and reasoning behind geological change.  The opening of the text establishes geologic study as a way to understand the history of the Earth through its rocks, including their formation, alteration, and the factors that have influenced their current states. Norton discusses the processes that lead to geological changes, emphasizing the importance of both external forces, such as weather and water, and internal movements such as earthquakes and volcanic activity. This introduction sets the stage for a detailed exploration of geological principles, aiming to ground readers in key concepts while making practical exercises available to reinforce learning.
