Class 9 Social Science - PUNJAB
Physical Features of India
The chapter 'Physical Features of India' in Class 9 Social Science explores the incredible diversity of India's landforms, ranging from the towering snow-clad Himalayas in the north to the vast Northern Plains, the rugged Peninsular Plateau, the Indian Desert, the coastal plains, and the picturesque islands. Based on the theory of Plate Tectonics, this chapter explains how these physical features were formed and how they influence India's climate, vegetation, drainage, and human life. For Punjab School Education Board (PSEB) exams, this is a high-scoring geography chapter that frequently features map work and structural questions.

Theory of Plate Tectonics
A scientific theory explaining that the Earth's crust is broken into seven major and several minor tectonic plates whose movement creates geological features like folds, faults, and volcanoes.
The Himalayan Mountains
Geologically young and structurally fold mountains stretching over the northern borders of India, consisting of three parallel ranges: Greater Himalayas (Himadri), Lesser Himalayas (Himachal), and Outer Himalayas (Shiwaliks).
The Northern Plains
Formed by the interplay of three major river systems—the Indus, the Ganga, and the Brahmaputra—these fertile plains are agriculturally very productive and densely populated.
The Peninsular Plateau
A tableland composed of old crystalline, igneous, and metamorphic rocks, broadly divided into the Central Highlands and the Deccan Plateau, rich in minerals.
Coastal Plains and Islands
Narrow strips of plain land flanking the Peninsular Plateau along the Arabian Sea and Bay of Bengal, accompanied by two major island groups: Lakshadweep and Andaman & Nicobar.
