There are many, including my environmental and civil engineering technology students, who do not have decades to commit to developing a working understanding of the Earth and the specific geological and geomorphological contexts they may find themselves working in. Therefore, this textbook is designed to provide a brief introduction to the concepts of geology and geomorphology, with an Ontarian perspective. It serves as a good starting point for individuals who have neither prior experience nor knowledge in geology nor geomorphology. In order to adequately explain concepts that unfold in four dimensions (3 dimensions with time as the fourth), an electronic format is used to leverage enhanced illustrations. These illustrations include traditional 2D figures; however, videos, animations, and interactive figures are also used to help create a deeper understanding.
