Population Size and Distribution As per the Census 2011, India's population was over 1.21 billion. Population is unevenly distributed across states: Highly populated: Uttar Pradesh, Maharashtra, Bihar Less populated: Sikkim, Mizoram, Lakshadweep Population Density:  Number of people living per square kilometer.

Chapter - 3  Drainage  What is Drainage? Drainage refers to the river system of an area. A drainage basin is the area drained by a single river system. A watershed is the boundary that separates two drainage basins. Drainage Basin A drainage basin is the area of land where all the water drains into a single river system. It includes the main river and all its tributaries. Think of it like a bowl: all the rain falling inside it flows toward the bottom (the main river). Water Divide (Watershed) A water divide is a highland or elevated area that separates two drainage basins. Water falling on one side of the divide flows into one river system, and on the other side, it flows into another. 2. Drainage Systems in India :-  India has two major types of drainage systems: a. Himalayan Rivers Perennial (flow all year round) Fed by glaciers and rain Long courses from source to sea Example: Ganga, Brahmaputra, Indus b. Peninsular Rivers Seasonal (depend on rainfall) Shorter and shal...

  Chapter - 2 Physical Features of India The Himalayan Mountains Location & Importance: Stretch along the northern border of India. Extend from Indus River (west) to Brahmaputra River (east). Approximate length: 2,400 km Width: 400 km (Kashmir) to 150 km (Arunachal Pradesh) The Himalayas act as a natural barrier, protect from cold winds, and influence monsoon patterns. Formation: Formed by the collision of the Indo-Australian Plate with the Eurasian Plate. This is a fold mountain range – still rising due to tectonic activity. Three Parallel Ranges: 1. Himadri (Greater Himalayas) Northernmost and highest range. Average height: Above 6,000 meters. Includes world’s highest peaks: Mount Everest (8,848 m) – Nepal Kanchenjunga (8,586 m) – India-Nepal border Covered with snow and glaciers all year round. 2. Himachal (Middle Himalayas) Lies south of Himadri. Height: 3,700 to 4,500 meters Made of folded and compressed rocks. Rich in forests. Famous hill stations: Shimla, Mussoorie, Nain...
