Yet, many of us rarely pause to consider how these landforms came to be, why they
LA-NET | ONLINE LEARNING VIDEO PLATFORM FOR POST-SECONDARY & HIGHER INSTITUTION STUDENTS differ across regions, or what they mean for human activity. Geomorphology, the scientific study of landforms and the processes that shape them, provides the key to unlocking these questions. By beginning with the foundations and scope of geomorphology, you will gain the essential background needed to appreciate the rest of this course and to connect the physical environment with human development. The aim of this Series is to introduce you to the meaning, scope, and relevance of geomorphology, while equipping you with the ability to explain its fundamental concepts and importance to society. We shall commence this Series by examining the meaning and scope of geomorphology, clarifying its definition and its links with other branches of geography. Then, we will explore the historical development of geomorphology, tracing early approaches and modern perspectives. Following that, we will move on to fundamental concepts such as landforms, classification, and the processes that shape the Earth’s surface. Finally, we will wrap up by considering the importance of geomorphology to society, including its role in resource management, settlement, and hazard assessment. Series Learning Outcomes Upon completing this Series, you should be able to: • SLO 1.1 define the meaning of geomorphology and explain its scope within the discipline of geography, • SLO 1.2 analyse the historical development of geomorphology by identifying key approaches and modern perspectives, • SLO 1.3 classify major types of landforms and explain the fundamental processes that shape the Earth’s surface, • SLO 1.4 evaluate the importance of geomorphology to society by discussing its role in resource management, settlement, and hazard assessment. 1.1 Meaning and Scope of Geomorphology 1.1.1 Definition of geomorphology The term geomorphology refers to the scientific study of landforms, their origin, evolution, and the processes that shape them. It combines the Greek words geo meaning Earth and morph meaning form, with logy meaning study. Geomorphology therefore focuses on the forms of the Earth’s surface and the dynamics that create and modify them.

It examines both large-scale features such as mountain ranges and small-scale features such as river terraces. The relevance of geomorphology lies in its ability to explain why landscapes differ across regions and how these differences influence human activity. Geomorphology also contributes to applied fields such as environmental management, urban planning, and hazard mitigation. For example, understanding slope processes helps in designing safe settlements, while knowledge of river systems aids in flood control.
LA-NET | ONLINE LEARNING VIDEO PLATFORM FOR POST-SECONDARY & HIGHER INSTITUTION STUDENTS Box 1.1: Applications of geomorphology in everyday life Fill in the blank: The scope of geomorphology includes the description, ________, and explanation of landforms. 1.1.3 Relationship with other branches of geography Geomorphology is closely linked with other branches of geography. It overlaps with physical geography, which studies natural processes and features, and with human geography, which examines how people interact with their environment. It also connects with disciplines such as geology, hydrology, and climatology, since landforms are shaped by rock structures, water movement, and climate conditions. This interdisciplinary nature makes geomorphology a central pillar of geographical studies. By integrating knowledge from related fields, geomorphologists can provide comprehensive explanations of landscape development.

LA-NET | ONLINE LEARNING VIDEO PLATFORM FOR POST-SECONDARY & HIGHER INSTITUTION STUDENTS 1.2 Historical Development of Geomorphology 1.2.1 Early approaches to landform study The study of landforms has a long history, beginning with early observations made by philosophers and explorers. In its earliest stage, geomorphology was descriptive, focusing on recording the shapes and appearances of landscapes without much emphasis on processes. Ancient scholars often linked landforms to myths or divine forces, while later naturalists began to recognise the role of natural processes such as rivers, wind, and glaciers. The descriptive tradition laid the foundation for systematic observation, which remains important today. By carefully noting landform features, early geomorphologists provided valuable records that modern scientists can analyse further. Fill in the blank: Early geomorphology was largely ________, focusing on recording shapes and appearances of landscapes. 1.2.2 Modern perspectives and scientific methods Modern geomorphology shifted from description to explanation, emphasising the processes that create and modify landforms. The introduction of scientific methods such as field surveys, laboratory experiments, and remote sensing allowed geomorphologists to analyse landscapes more accurately. One key development was the recognition of geomorphic processes, defined as the natural mechanisms such as erosion, weathering, and deposition that shape the Earth’s surface. These processes operate over different timescales, from sudden events like landslides to gradual changes like soil formation.

For example, knowledge of river systems helps in flood management, while understanding coastal processes aids in protecting shorelines. Geomorphology also supports sustainable development by guiding land use planning and resource management. By predicting areas prone to hazards such as landslides or erosion, geomorphologists help communities prepare and adapt.
