- South-West Monsoon blows from June to September in India.
- Winds move from South-West to North-East (shown by arrows).
- It has two branches: Arabian Sea branch and Bay of Bengal branch.
- It is also called the Advancing Monsoon or Summer Monsoon.
- These winds bring maximum rainfall to most parts of India.
Key Points
Key Points: Physical and Political Features of India – Map Work
- Physical features include major mountain ranges, peaks, plateaus, plains, deserts, rivers, and water bodies of India.
- Important mountains and plateaus are the Himalayas, Western & Eastern Ghats, Nilgiris, Deccan Plateau, and Chota Nagpur Plateau.
- Major plains and water bodies include the Gangetic Plains, Coastal Plains, Gulfs, seas, straits, and lakes.
- Climatic factors include the Tropic of Cancer, Standard Meridian, monsoon winds, and western disturbances.
- Human geography includes important cities, mineral distribution, soil types, rivers, and population distribution (dense/sparse).
Key Points: Mountains, Peaks, Passes and Plateaus of India
- Himalayas & Karakoram run west–east in the north; K2 and Kanchenjunga are major peaks.
- Aravalli, Vindhya & Satpura ranges lie in central India; Aravalli is very old.
- Western Ghats (continuous) and Eastern Ghats (broken) meet at the Nilgiris.
- Deccan Plateau lies south of the Narmada; Chota Nagpur Plateau is mineral-rich.
- Important passes include Karakoram Pass and Nathu La Pass.
Key Points: Plains, Desert of India
- Gangetic Plains: Fertile plains formed by rivers like Ganga–Brahmaputra; densely populated.
- Thar Desert: Hot, dry desert in north-west India with sand dunes and scanty rainfall.
- Western Coastal Plains: Narrow plains along Arabian Sea—Konkan, Kanara and Malabar coasts.
- Eastern Coastal Plains: Broad plains along Bay of Bengal—Northern Circars and Coromandel coast.
- Key fact: Eastern Coastal Plains are wider than Western Coastal Plains.
Key Points: Rivers and Water Bodies of India
- Indian rivers are divided into Himalayan rivers (Indus, Ganga, Brahmaputra) and Peninsular rivers (Narmada, Godavari, Krishna, Cauvery, etc.).
- Himalayan rivers are long, perennial and form fertile plains and large river systems.
- Peninsular rivers are shorter, mostly seasonal and flow from plateaus to seas.
- Rivers are shown in light blue and marked with arrows showing flow direction within India.
- Important water bodies include Gulfs (Kutch, Khambhat, Mannar), straits (Palk Strait) and lakes like Chilika (brackish) and Wular (freshwater).
Key Points: Latitude and Longitude of India
- Tropic of Cancer (23½°N) passes almost through the middle of India.
- It divides India into Tropical (south) and Sub-tropical (north) regions.
- Standard Meridian of India = 82°30′ E longitude.
- The Standard Meridian passes near Prayagraj (Allahabad), Uttar Pradesh.
- It is used to fix Indian Standard Time (IST) for the whole country.
Key Points: Direction of South-West Monsoon Winds in India
Key Points: Direction of North-East Monsoon Winds in India
- Western Disturbances are temperate cyclones coming from the Mediterranean region.
- They move towards north-west India (Punjab, Haryana, western Himalayas).
- They cause winter rainfall in plains and snowfall in mountains.
- North-East Monsoon winds blow from land to sea (north-east to south-west).
- They give winter rain to the Coromandel Coast (Tamil Nadu) and are called Retreating Monsoon.
Key Points: Distribution of Minerals in India
- Coal → Jharia (Jharkhand) – largest coalfield in India.
- Iron ore → Singhbhum (Jharkhand).
- Oil (onshore) → Digboi (Assam) – oldest oilfield in India.
- Oil (offshore) → Mumbai High (Arabian Sea) – largest domestic oil source.
- Map marking rule → Minerals are shown by small dots on maps.
Key Points: Soil Distribution of India
- Alluvial soil is found in the Ganga–Brahmaputra plains and coastal plains; it is very fertile.
- Black soil occurs mainly in the Deccan Plateau and is formed from lava rocks.
- Red soil is formed by weathering of crystalline rocks and is found in southern and eastern India.
- Laterite soil develops in high rainfall areas due to leaching, especially along the Western & Eastern coasts.
- Alluvial soil is river-deposited, while black, red and laterite soils depend on rock type and climate.
Key Points: Cities in India
- Major cities marked by dots (e.g., Delhi, Mumbai, Kolkata, Chennai).
- Coastal cities (Mumbai, Chennai, Kochi, Visakhapatnam) touch the sea.
- Delhi lies on River Yamuna.
- Prayagraj (Allahabad) is at the confluence of Ganga and Yamuna.
- Cities are classified by population (Megacity, Metropolis, Sub-metropolis).
Key Points: Distribution of Population in India
- Dense population → Northern plains (Ganga–Brahmaputra region).
- Highest density (2011) → Bihar; also high in West Bengal & Kerala.
- Sparse population → Himalayan region, Thar Desert, North-East hills.
- Kerala → Most densely populated state in South India.
- Population density = Number of persons per sq. km.
