NCERT Class 11 Geography, India Physical Environment Chapter 2 titled संरचना तथा भूआकृतिक विज्ञान (Structure and Geomorphology) introduces students to the internal structure of the Earth and the processes that shape landforms. This chapter explains how forces working inside and on the surface of the Earth create mountains, plateaus, plains, valleys, and other physical features. It acts as a bridge between basic Earth science and physical geography.
I am writing about this chapter because many students find geomorphology slightly difficult at first, but once the concepts are clear, it becomes one of the most interesting parts of geography. This chapter helps you understand why earthquakes happen, how volcanoes form, and why different landforms exist across the world. For board exams, questions are often direct and concept-based. Having the NCERT PDF and revising with clear explanations can make a big difference in your preparation.
What This Chapter Covers
Chapter 2 focuses on Earth’s structure and geomorphic processes.
- Interior of the Earth
- Earth’s crust, mantle, and core
- Endogenic (internal) and exogenic (external) forces
- Plate tectonics
- Origin of major landforms
Structure of the Earth
The Earth is divided into three main layers.
- Crust – The outermost layer where we live
- Mantle – The layer beneath the crust, rich in magma
- Core – The innermost layer, mainly composed of nickel and iron
Understanding these layers helps explain volcanic activity and earthquakes.
Geomorphic Processes
Geomorphic processes are natural forces that shape the Earth’s surface.
Endogenic Forces
These originate inside the Earth.
- Earthquakes
- Volcanic eruptions
- Folding and faulting
They mainly create mountains and plateaus.
Exogenic Forces
These operate on the Earth’s surface.
- Weathering
- Erosion
- Deposition
They help in forming valleys, plains, and coastal features.
Plate Tectonics and Landform Development
The movement of tectonic plates explains:
- Formation of fold mountains like the Himalayas
- Occurrence of earthquakes along plate boundaries
- Creation of ocean basins and rift valleys
This topic is important for both theory and map-based questions.
Why This Chapter Is Important for Students
- Builds foundation for physical geography
- Helps understand natural disasters
- Frequently asked in board exams
- Useful for competitive exams
