Geomorphology for UPSC: Complete Topic-wise Notes

Geomorphology is a core component of Physical Geography in the UPSC Civil Services Examination. It deals with the origin and evolution of the Earth, internal structure, plate tectonics, and the processes responsible for shaping landforms. A strong understanding of geomorphology is essential for both Prelims and Mains, especially for analytical and concept-based questions.

This page serves as a comprehensive repository of geomorphology topics, providing structured access to detailed articles for systematic and effective UPSC preparation.

Origin and Evolution of the Earth

Understanding the origin of the Earth and its evolution provides the foundation for studying geomorphic processes and landform development.

• Origin and Evolution of the Earth 

Interior of the Earth

The structure of the Earth, including its layers and composition, is crucial for understanding tectonic movements and geological processes.

• Interior of the Earth 

Geology and Rock System

Rocks form the basic building blocks of the Earth’s crust and play a significant role in landform development.

• Geology and Rock System 

Continental Drift and Plate Tectonics

The movement of continents and tectonic plates explains the distribution of landforms, earthquakes, and volcanic activity.

• Theory of Continental Drift (Basis of Plate Tectonics)
• Plate Tectonics Theory 

Sea Floor Spreading and Convectional Currents

These theories explain the mechanism behind plate movements and the formation of oceanic crust.

• Sea Floor Spreading/Convectional Current Theory 

Earth Movements and Tectonic Activities

Tectonic forces lead to sudden and slow movements within the Earth, resulting in various geological phenomena.

• Earthquakes
• Volcanism

Geomorphic Processes

Geomorphic processes shape the Earth’s surface through internal and external forces.

• Geomorphic Processes (Endogenic and Exogenic)

Landforms and Their Evolution

Landforms are the visible features of the Earth’s surface, formed through continuous geomorphic processes over time.

• Landforms and Their Evolution
• Karst Topography
