Chapter Overview
Shaping of the Earth’s Surface is Chapter 2 of the new Class 9 Social Science textbook Exploring Society: India and Beyond. This Geography chapter explores how the Earth’s surface is continuously shaped and reshaped by processes operating within the Earth and on its surface.
Students learn about plate tectonics, the interior of the Earth, weathering and erosion, different agents of gradation, the formation of landforms, and natural disasters such as earthquakes, landslides, avalanches and Glacial Lake Outburst Floods (GLOFs).

About This Chapter
The Earth’s surface is not static. It is continuously modified by powerful natural processes. Some processes originate inside the Earth, while others operate on or near its surface.
In this chapter, students explore how plate tectonics and movements within the Earth contribute to major changes in the Earth’s surface. They also study the role of weathering, erosion and deposition in gradually modifying landscapes.
Rivers, waves and currents, wind, glaciers and underground water act as important agents in shaping different landforms. The chapter also connects geographical processes with hazards such as earthquakes, landslides, avalanches and Glacial Lake Outburst Floods.
The chapter therefore helps students understand that the Earth’s surface is a dynamic system that changes over time.
Learning Outcomes
After completing this chapter, students should be able to:
- explain the theory of plate tectonics
- understand how tectonic plates influence Earth’s surface
- locate major tectonic plates on a world map
- describe the interior of the Earth
- explain the processes of weathering and erosion
- identify different agents of gradation
- explain how rivers, waves, wind, glaciers and underground water modify landforms
- identify major landforms and explain their formation
- understand the relationship between internal and external processes
- explain the causes of selected natural disasters
- suggest appropriate measures for disaster mitigation
These outcomes closely follow the 2026–27 syllabus material available for the chapter.

❓FAQ
Q1. What is Class 9 Social Science Chapter 2 about?
Chapter 2, “Shaping of the Earth’s Surface,” explains how internal and external geographical processes continuously shape and modify the Earth’s surface.
Q2. What is plate tectonics?
Plate tectonics is a theory that explains the movement of large tectonic plates forming the Earth’s outer rigid layer and their role in shaping the Earth’s surface.
Q3. What are the main topics in Chapter 2?
The chapter covers plate tectonics, the interior of the Earth, weathering, erosion, agents of gradation, landforms and natural disasters.
Q4. What is weathering?
Weathering is the breakdown or alteration of rocks at or near the Earth’s surface. It contributes to the gradual modification of landscapes.
Q5. What is erosion?
Erosion is the wearing away and removal of material from the Earth’s surface by agents such as running water, wind, glaciers and waves.
Q6. Which agents help shape the Earth's surface?
Important agents discussed in the chapter include rivers, waves and currents, wind, glaciers and underground water
Q7. What are landforms?
Landforms are natural physical features of the Earth’s surface, such as mountains, valleys and plains, formed and modified by different geographical processes.
Q8. Which natural disasters are covered in Chapter 2?
The chapter includes earthquakes, landslides, avalanches and Glacial Lake Outburst Floods (GLOFs) as natural hazards associated with the changing Earth’s surface
Q9. Is Chapter 2 part of Geography?
Yes. Shaping of the Earth’s Surface is Chapter 2 and is the first chapter under the Geography section of the new Class 9 Social Science textbook.
Q10. What resources are available for Chapter 2?
Students can use chapter notes, practice questions, MCQs, competency-based questions, worksheets, maps and diagrams, revision resources and NCERT exercise support, depending on the resources available on this page.
