Rivers, Mountains and Landscapes of India: quick revision, 22 bites

India's 5 Major Landforms

Five landforms shape all of India.

A **landform** is a natural feature of the Earth's surface. India has five major kinds, each with a distinct look and way of life.

Takeaway. Plain = flat + low; Plateau = flat + high + steep edges.

Plain vs Plateau: The Flat-Top Difference

Both are flat — only one is high.

Takeaway. A plateau is a raised flatland; a plain is a low flatland.

K2: Karakoram's Highest Peak

World's second-highest, India's Karakoram star.

**K2 (Godwin-Austen)** is the highest peak of the **Karakoram** range and the **world's second-highest peak**.

Takeaway. K2 = Karakoram's highest = world's 2nd highest.

Himalayan vs Peninsular Rivers

Two river families, two very different habits.

Takeaway. Glacier-fed = perennial; rain-fed = seasonal.

Mountain Ranges of India — Quick Map

Six ranges, six locations, six facts.

Takeaway. Himalayas = youngest; Aravalli = oldest; Vindhya = N-S divider.

Narmada Flows Between Two Parallel Ranges

A river in a rift between twins.

Takeaway. Vindhya + Satpura sandwich the Narmada.

Himalayan Rivers — Source to Mouth

Where each great river starts and ends.

Takeaway. Indus → Arabian Sea; Ganga, Brahmaputra → Bay of Bengal.

Peninsular Rivers — Source to Mouth

Six rivers, two seas, one plateau slope.

Takeaway. Only Narmada & Tapi flow west; the rest go east.

Only 3 Rivers Flow West

Three rebels flow the other way.

Almost every Indian river flows **east into the Bay of Bengal**. Only **three** flow **west into the Arabian Sea**:

Takeaway. Remember: 'I-N-T go West' — Indus, Narmada, Tapi.

Delta vs Estuary — Don't Mix Them Up

Triangle or funnel? Look at the mouth.

Takeaway. Delta = triangle; Estuary = funnel.

River Vocabulary You Must Know

Six river words every exam asks.

Takeaway. Tributary joins in; distributary branches out.

The Himalayas Are Still Growing

1 cm taller every single year.

The **Himalayas grow about 1 cm taller every year** due to the slow collision of tectonic plates — they are the **world's youngest** mountain range.

Takeaway. Youngest range = still rising.

Ganga: Longest River in India

2,525 km — India's longest river.

The **Ganga** is the **longest river flowing in India** — about **2,525 km**. Its confluence with the Yamuna at Prayagraj is called the **Triveni Sangam** (the third, invisible river being the Saraswati).

Why Peninsular Rivers Flow East

The plateau tilts — rivers obey gravity.

The Godavari, Krishna, and Kaveri rise in the **Western Ghats** yet flow **east** into the Bay of Bengal. Why?

Takeaway. Deccan Plateau slopes west → east, so rivers flow east.

Water Storage: Dams & Reservoirs

Where does dry-season water hide?

Takeaway. Dams store, irrigate, electrify, and control floods.

Drought vs Flood

Too little water vs too much water.

Takeaway. Drought = save water; Flood = dams + embankments + trees.

Three phases, three checklists.

Takeaway. Prepare → Protect → Purify: safety at every phase.

Water Pollution: Causes & Prevention

Four causes, three fixes.

Takeaway. Stop dumping, treat sewage, keep water bodies clean.
