India — Geography and States

Overview

India's geography forms a crucial component of Environmental Studies for MAHA TET Paper I. This topic tests your knowledge of India's physical features, political divisions, major rivers, and the spatial relationships between states and their capitals. Understanding Indian geography helps teachers connect children to their immediate environment and gradually expand their awareness to the national level.

For the exam, expect questions on identifying states and capitals, locating rivers and mountain ranges, and understanding how physical features influence climate and human settlements. Questions often involve map-based reasoning, matching exercises, and factual recall about India's 28 states and 8 Union Territories. This topic integrates well with themes of diversity, resources, and regional cultures that primary students explore in EVS.

Mastery requires memorising state-capital pairs, tracing major rivers from source to mouth, and visualising India's physical divisions — the Himalayas, plains, plateaus, deserts, and coastal regions.

Key Concepts

• **Political Divisions**: India has 28 states and 8 Union Territories. States have elected governments; UTs are administered directly or partially by the Central Government.

• **Physical Divisions of India**: The country is divided into six major physiographic regions — the Himalayan Mountains, the Northern Plains, the Peninsular Plateau, the Coastal Plains, the Thar Desert, and the Islands.

• **The Himalayas**: Young fold mountains in the north acting as a natural barrier. Three parallel ranges — Himadri (Greater Himalayas), Himachal (Lesser Himalayas), and Shiwaliks (Outer Himalayas).

• **The Northern Plains**: Formed by alluvial deposits of Indus, Ganga, and Brahmaputra river systems. Extremely fertile and densely populated.

• **The Peninsular Plateau**: Ancient landmass comprising the Deccan Plateau, flanked by Western Ghats and Eastern Ghats. Rich in minerals.

• **River Systems**: India has Himalayan rivers (perennial, snow-fed) and Peninsular rivers (rain-fed, seasonal). Major river basins include Ganga, Brahmaputra, Indus, Godavari, Krishna, Kaveri, Narmada, and Tapi.

• **Drainage Patterns**: Most peninsular rivers flow eastward into the Bay of Bengal. Narmada and Tapi are exceptions — they flow westward into the Arabian Sea through rift valleys.
