Study Notes
Definition
- Geomorphology is the scientific study of landforms, their processes, origins, and development.
Key Concepts
-
Landforms:
- Natural structures on the Earth's surface (e.g., mountains, valleys, plateaus).
- Classified into major categories: hills, plains, mountains, and valleys.
-
Processes:
- Endogenic: Internal processes like tectonics and volcanism.
- Exogenic: External processes such as weathering, erosion, and sedimentation.
-
Types of Geomorphology:
- Physical Geomorphology: Focuses on landform processes and development.
- Historical Geomorphology: Examines the history and evolution of landforms over time.
- Applied Geomorphology: Addresses practical applications in environmental management and planning.
Major Landform Processes
-
Weathering:
- Breakdown of rocks by mechanical, chemical, or biological means.
-
Erosion:
- Removal of soil and rock by wind, water, or ice.
-
Transport:
- Movement of weathered material from one location to another.
-
Deposition:
- Accumulation of sediments in new locations, forming new landforms.
Influencing Factors
- Climate: Affects weathering rates and erosion processes.
- Vegetation: Stabilizes soil and influences erosion.
- Human Activity: Urbanization, agriculture, and mining impact geomorphic processes.
Geomorphological Mapping
- Utilizes tools like GIS and remote sensing to study and analyze landforms.
- Helps in understanding spatial distribution and changes in landforms.
Applications
- Environmental Management: Land use planning, disaster risk assessment.
- Geological Studies: Understanding Earth’s history and climate change effects.
- Infrastructure Development: Designing roads, bridges, and buildings considering terrain.
Key Terms
- Tectonic Activity: Movement of the Earth's crust leading to the formation of mountains and earthquakes.
- Sedimentology: Study of sediments and sedimentary processes.
- Fluvial Processes: Related to rivers and streams, significant for shaping landscapes.
Notable Landform Types
- Glacial Landforms: Created by the action of glaciers (e.g., moraines, fjords).
- Karst Topography: Features formed from the dissolution of soluble rocks (e.g., caves, sinkholes).
- Desert Landforms: Formed in arid environments, includes dunes and plateaus.

- Historical: Focuses on landform evolution and history.
- Applied: Deals with practical implications in environmental management and planning.
Major Landform Processes
-
Weathering:
- Breakdown of rocks through mechanical, chemical, or biological methods.
-
Erosion:
- Removal of soil and rock driven by wind, water, or ice.
-
Transport:
- Movement of weathered materials to new locations.
-
Deposition:
- Accumulation of sediments in new sites, creating new landforms.
Influencing Factors
- Climate: Influences weathering rates and erosion dynamics.
- Vegetation: Plays a role in soil stabilization and reducing erosion.
- Human Activity: Urbanization, agriculture, and mining modify geomorphic processes.
Geomorphological Mapping
- Employs GIS and remote sensing for studying and analyzing landforms.
- Aids in understanding spatial distribution, changes, and impacts on landscapes.
Applications
- Environmental Management: Key for land use planning and assessing disaster risks.
- Geological Studies: Essential for exploring Earth’s history and impact of climate change.
- Infrastructure Development: Important for designing roads, bridges, and buildings with terrain considerations.
Key Terms
- Tectonic Activity: Movement of the Earth’s crust, responsible for mountains and earthquakes.
- Sedimentology: The study of sediments and their deposition processes.
- Fluvial Processes: Processes associated with rivers and streams, crucial in shaping landscapes.
Notable Landform Types
- Glacial Landforms: Features like moraines and fjords formed by glaciers.
- Karst Topography: Characterized by features like caves and sinkholes due to rock dissolution.
- Desert Landforms: Includes dunes and plateaus, shaped by arid environmental conditions.
