The Himalayas were formed in the Tertiary period due to the collision of the Indian and Eurasian plates. Their steep, sharp peaks, high seismic activity and ongoing uplift indicate they are young fold mountains.
Because they were formed recently by the folding of the Earth's crust when the Indian plate collided with the Eurasian plate; they are still rising and are geologically young.
Himalayan rivers:
- Origin: glaciers/snow in the Himalayas.
- Course: long, large drainage basins; meandering plains.
- Regime: perennial (fed by snow/glaciers and monsoon).
- Features: deep gorges in upper course, extensive alluvial plains (e.g., Indo-Gangetic Plain).
- Examples: Ganga, Brahmaputra, Indus.
Peninsular rivers:
- Origin: Deccan plateau/Western Ghats/Eastern Ghats.
- Course: shorter, shallower basins; older and more stable channels.
- Regime: seasonal (depend mainly on monsoon); many are non-perennial.
- Features: rapids and waterfalls, wider valleys, mostly east-flowing.
- Examples: Godavari, Krishna, Kaveri, Narmada (west-flowing exception), Tapi.
See key differences below.
The Kosi River is called the 'Sorrow of Bihar' because it frequently causes devastating floods and has a shifting course that damages life and property in Bihar.
Kosi River.
Himalayan origin provides continuous supply from melting snow and glaciers; monsoon rains supplement flow, making these rivers perennial.
They are fed by glacier and snow melt from the Himalayas and by monsoon rains, so they flow throughout the year.
Western Ghats:
- Location: along the western coast from Gujarat to Kerala.
- Orientation: north–south, continuous and high.
- Elevation: higher peaks (Anamudi ~2,695 m).
- Rainfall: receive heavy southwest monsoon rain; cause rain shadow to the east.
- Rivers: many short west-flowing rivers; heavy perennial streams on windward side.
Eastern Ghats:
- Location: along the eastern coast from Odisha to Tamil Nadu.
- Orientation: fragmented, discontinuous hills.
- Elevation: lower and more eroded.
- Rainfall: receive less direct monsoon rainfall; more dependent on northeast monsoon in south.
- Rivers: many east-flowing rivers (e.g., Godavari, Krishna) originate in central highlands rather than Ghats.
See main distinguishing features below.
- a. Coast
- b. Island
- c. Peninsula
- d. Strait
A peninsula is a landmass surrounded by water on three sides (e.g., Indian Peninsula).
c
The general eastward slope of the Deccan Plateau and the position of the Western Ghats cause many peninsular rivers (Godavari, Krishna, Kaveri) to flow east into the Bay of Bengal; west-flowing rivers are fewer and shorter.
Because the peninsular plateau generally slopes eastwards, most rivers flow from the plateau to the Bay of Bengal.
Western Coastal Plains:
- Location: between Western Ghats and Arabian Sea.
- Width: narrow (100–150 km on average, very narrow in south).
- Features: presence of estuaries, few lagoons and backwaters (Kerala), many ports on west coast.
- Rivers: short west-flowing rivers with estuaries.
Eastern Coastal Plains:
- Location: between Eastern Ghats and Bay of Bengal.
- Width: broader (up to 500 km in places).
- Features: extensive deltas and fertile plains (e.g., Ganga–Brahmaputra delta, Mahanadi, Godavari deltas), more lagoons in parts.
- Rivers: many long east-flowing rivers forming large deltas; good for agriculture.

Recent geological formation (Tertiary), active tectonics, sharp peaks and ongoing uplift indicate their youth as fold mountains.
They formed recently by folding due to the Indian–Eurasian plate collision and are still rising, showing steep relief and seismic activity.
Continuous supply from melting snow and glaciers in the Himalayas plus monsoon precipitation ensures flow year-round, making them perennial.
Because they are fed by Himalayan snow and glacier melt and by monsoon rains throughout the year.
The Deccan Plateau slopes eastward; the Western Ghats form a divide causing many rivers to originate on the western edge but flow eastwards across the plateau towards the Bay of Bengal.
Because the general slope of the peninsular plateau is eastward, directing most rivers to flow into the Bay of Bengal.
Himalayan rivers: glacier-fed, perennial, long courses, form large alluvial plains, major rivers like Ganga and Brahmaputra.
Peninsular rivers: monsoon-fed, mostly seasonal, shorter and older, flow through plateau with rapids and waterfalls, examples: Godavari, Krishna, Kaveri, Narmada.
See concise distinguishing points.
Western Ghats: continuous, higher, west-coast barrier causing heavy rainfall on windward side. Eastern Ghats: broken, lower, run parallel to east coast, less continuous and more eroded; different influence on rivers and rainfall patterns.
See concise distinguishing features.
Western Coastal Plains: narrow, between Western Ghats and Arabian Sea, estuaries and backwaters, shorter rivers; Eastern Coastal Plains: wider, between Eastern Ghats and Bay of Bengal, extensive deltas of major rivers, very fertile agricultural land.

India shares land borders with Pakistan (west), China and Nepal and Bhutan (north and northeast), Bangladesh and Myanmar (east). Sri Lanka and Maldives are neighbouring island nations (maritime neighbours).
Pakistan, China, Nepal, Bhutan, Bangladesh, Myanmar; maritime neighbours: Sri Lanka and Maldives.
Importance: ensures uniform time for administration, railways, broadcasting and communication across India; simplifies scheduling and coordination. Note: a single time zone can cause early sunrises in the east and late sunsets in the west, which is a practical drawback but operational uniformity is the main benefit.
Indian Standard Time (IST) provides a single uniform time for the entire country (UTC+5:30) based on the 82°30'E meridian (near Mirzapur).
Travelling along the coast from West Bengal (east coast) around the southern tip up the west coast to Gujarat would pass the east coast states Odisha and Andhra Pradesh, then along the southern coast through Tamil Nadu and Kerala (rounding Kanyakumari), then northwards through Karnataka, Goa, Maharashtra and finally Gujarat. (Union territories such as Puducherry may also be encountered.)

Key points:
- Location: Arabian Sea, about 200–450 km off Kerala coast.
- Composition: 36 islands (coral atolls, reefs and lagoons); around 10–12 inhabited.
- Capital: Kavaratti (Union Territory administration).
- Economy: fishing, coconut, coir, small‑scale agriculture and tourism.
- Environment: coral formations, lagoons, rich marine life; ecologically sensitive — conservation important.
Lakshadweep is a group of coral islands in the Arabian Sea off the coast of Kerala; it is a Union Territory with Kavaratti as its capital. The archipelago consists of 36 islands (about 10–12 inhabited), formed mainly of coral atolls, reefs and lagoons. Economy: fishing, coconut cultivation, coir and growing tourism. Climate: tropical maritime. Important features: fragile coral ecosystem, lagoons, and rich marine biodiversity.
Divisions: Trans-Himalaya/Karakoram (northwestern), Greater Himalaya (Himadri)—highest peaks, Lesser Himalaya (Himachal)—middle ranges, Outer Himalaya (Shivalik)—foothills. Importance: climatic barrier, rivers source, water for irrigation/hydel power, biodiversity, strategic defence, tourism.
The Northern Mountains (the Himalaya) are divided into three main parallel ranges: the Greater Himalaya (Himadri) with the highest peaks and permanent snow; the Lesser Himalaya (Himachal) consisting of steep valleys and hill ranges; and the Outer Himalaya (Shivalik) of lower elevation with young sediments. Some classifications include the Trans-Himalayan ranges (e.g., Karakoram) to the north. Importance: they act as a climatic barrier protecting the subcontinent from cold Central Asian winds and helping retain monsoon rainfall; they are the source of major perennial rivers (Ganga, Brahmaputra and their tributaries) vital for irrigation and hydropower; they harbour rich biodiversity and forests; they are important strategic frontiers and attract tourism and pilgrimage.
Godavari (longest peninsular river) and Krishna originate on the Deccan plateau and flow east into the Bay of Bengal; Kaveri flows from the Western Ghats to the southeast; Mahanadi drains central-eastern India. Narmada and Tapi flow west across narrow coastal plains into the Arabian Sea. Their dams and canals are crucial for irrigation and power.
Major peninsular rivers include the Godavari, Krishna, Kaveri, and Mahanadi (east-flowing) and the Narmada and Tapi (west-flowing). The east-flowing rivers originate in the Western Ghats or central highlands and drain into the Bay of Bengal forming fertile deltas important for agriculture. The Narmada and Tapi flow westwards into the Arabian Sea, usually through rift valleys and have shorter courses. These rivers support irrigation, hydroelectric power, inland navigation in places, and sustain regional agriculture and settlements.
Key points: source in Himalaya; major tributaries (Yamuna, Ghaghara, Gandak, Kosi, Son); covers several states (Uttarakhand, UP, Bihar, Jharkhand and West Bengal) and Bangladesh; fertile alluvial soils; supports agriculture, settlements, transport and culture; flood-prone but agriculturally productive.
The Ganga basin is one of the largest alluvial basins in the world, covering parts of northern and eastern India and Bangladesh. It originates in the Himalaya (confluence of Bhagirathi and Alaknanda) and flows southeast across the plains, receiving major tributaries like the Yamuna, Ghaghara, Gandak, Kosi (from the north/right) and the Son (from the south/left). The basin includes diverse landscapes from high mountains to fertile Gangetic plains with rich alluvium (Bhangar and Khadar). It supports dense population, intensive agriculture (rice, wheat, sugarcane), major cities, river transport, and extensive irrigation and hydropower systems. The basin is culturally significant and prone to seasonal floods that replenish soils but also cause damage.
On the map, mark and label: Deccan Plateau bounded by Western and Eastern Ghats (south-central India); Karnataka and Maharashtra portions within Deccan; Central Highlands (includes Malwa Plateau) north of Deccan; Chota Nagpur Plateau in Jharkhand (east); and smaller plateaus like Meghalaya in the northeast peninsular fringe. Use state boundaries as reference while marking.
Major plateau divisions: Deccan Plateau (including Karnataka Plateau, Maharashtra uplands), Central Highlands (Malwa plateau, Bundelkhand), Chota Nagpur Plateau (eastern plateau in Jharkhand/Odisha), Meghalaya Plateau (northeast), Gujarat Plains and Rann uplands (northwest peninsular fringe).
