Class 9 Social Science - CBSE
Physical Features of India
The chapter 'Physical Features of India' explores the diverse geological landscape of the country, ranging from the towering Himalayas in the north to the vast Northern Plains, the rugged Peninsular Plateau, the Indian Desert, the Coastal Plains, and the island groups. You will learn how plate tectonics, weathering, and erosion shaped these landforms over millions of years. This chapter is vital for CBSE Class 9 board exams because it forms the geographical foundation for understanding India's climate, drainage, and natural vegetation, frequently appearing in map-pointing and long-answer questions.

Theory of Plate Tectonics
The Earth's crust is broken into seven major and minor plates whose movement creates geological stress, leading to folding, faulting, and volcanic activity that formed India's physical features.
The Himalayan Mountains
A young fold mountain system stretching along India's northern borders, consisting of three parallel ranges: the Great Himalayas (Himadri), the Lesser Himalayas (Himachal), and the Outer Himalayas (Shiwaliks).
The Northern Plains
Formed by the interplay of the Indus, Ganga, and Brahmaputra river systems, these fertile plains are heavily populated and divided into four regions: Bhabur, Terai, Bhangar, and Khadar.
The Peninsular Plateau
An ancient tableland composed of crystalline, igneous, and metamorphic rocks, broadly divided into the Central Highlands and the Deccan Plateau, rich in minerals.
Coastal Plains and Islands
The narrow coastal strips flanking the Peninsular Plateau (Konkan, Kannad, Malabar on the west; Coromandel and Northern Circar on the east), alongside the Lakshadweep and Andaman & Nicobar island groups.

Board Exam Info
This chapter typically carries 5 to 8 marks in the CBSE Class 9 Social Science (Geography) exam. Common question types include direct short answers, differentiation questions (e.g., Bhangar vs. Khadar, Eastern Ghats vs. Western Ghats), and mandatory Map Skill-based questions identifying mountain ranges, peaks, and plateaus.
Frequently Asked Questions
What is the difference between Bhangar and Khadar?
Bhangar is older alluvium located above the flood plains with calcareous deposits called kankar, whereas Khadar is newer, more fertile alluvium deposited by floodwaters annually.
How were the Himalayas formed?
The Himalayas were formed due to the collision of the Indo-Australian plate with the Eurasian plate, which compressed the sedimentary rocks of the Tethys Sea into fold mountains.
What are the major physiographic divisions of India?
India is divided into six physical divisions: the Himalayan Mountains, the Northern Plains, the Peninsular Plateau, the Indian Desert, the Coastal Plains, and the Islands.
