World and Human Geography — NDA Geography
This is the 'atlas' chapter of NDA Geography — 25 PYQs across 2017–2026 that reward a student who has actually looked at a world map. Almost none of it is derivation; it is named-fact recall: which river drains where, which canal links which seas, where the Prime Meridian runs, which city was the first megacity, where a famous desert sits. The marks come from coverage, not cleverness, so the chapter is built as a set of reference tables you drill until the names stick — plus a small handful of 'why' concepts (longitude and local time, the International Date Line) that follow a simple rule rather than a list. It teaches in three movements, from physical features to coordinates to people: (1) World rivers, canals and water bodies — the Suez and Panama canals, landlocked seas, the Great Artesian Basin, Ramsar wetlands; (2) Coordinates, time and place — latitude/longitude, GMT offsets, the Prime Meridian and the International Date Line; (3) Human geography — megacities, population density, and the world-places gazetteer (deserts, mountains, island groups, organisation headquarters). 11 concepts, every PYQ tagged. The questions skew EASY-to-MODERATE; the only HARD ones hide a place-fact inside a multi-statement stem.
Subtopic notes
World Rivers, Canals and Water Bodies
6 PYQsThe world's two great ship canals (Suez and Panama), the seas they link, the landlocked water bodies, and a few named river/wetland facts the NDA returns to.
Open note
World Coordinates, Time and Place
4 PYQsHow latitude and longitude fix a place on the globe, how longitude controls local time (GMT offsets, the Prime Meridian) and what happens when you cross the International Date Line.
Open note
Human Geography — Megacities, Population and World Places
15 PYQsMegacities and the three population-density measures, plus the world-places gazetteer the NDA draws on — deserts, mountains, island groups, landlocked countries and the headquarters of global organisations.

Reference tables (2)
The Suez and Panama Canals2 rows
| Canal | Links | Locks? | Opened |
|---|---|---|---|
| Suez | Mediterranean Sea ↔ Red Sea | NO locks | 1869 NDA 2019 — the 'six lock system' claim about Suez is the FALSE statement (Suez is sea-level, no locks). |
| Panama | Atlantic Ocean ↔ Pacific Ocean | Has locks | 1914 |
Landlocked seas, rivers and wetlands4 rows
| Feature | Key fact |
|---|---|
| Landlocked water body | Caspian Sea NDA 2024 — the Caspian Sea is landlocked; the Mediterranean, Black and Red Seas are not. |
| Helmand River | Hindu Kush → Hamoun wetlands; Afghanistan–Iran water dispute NDA 2023 — identify the river by the Hindu Kush origin + Hamoun destination. |
| Great Artesian Basin | Mostly under Queensland, Australia |
| India's Ramsar sites | 27 (as tested) |
Watch out for (2)
- Suez has no locks; Panama does→ The Suez and Panama Canals
- The Caspian is a 'Sea' in name but landlocked in fact→ Landlocked seas, rivers and wetlands
Watch out for (2)
- East = ahead, but the DATE line is the opposite→ Longitude, GMT offsets and the Prime Meridian
- East across the date line LOSES 24 hours→ The International Date Line
Reference tables (3)
World deserts and country nicknames3 rows
| Place | Fact |
|---|---|
| Atacama | World's driest desert (South America) NDA 2018 — Atacama is the driest desert, not the Sahara or Gobi. |
| Taklamakan | Cold desert of Central Asia (China) NDA 2017 — Taklamakan is in Central Asia. |
| Denmark | Called the 'country of winds' NDA 2020 — Denmark is the 'country of winds'. |
Rivers, mountains, oceans and island groups5 rows
| Place | Fact |
|---|---|
| Mekong Delta | Vietnam |
| Caucasus Mountains | Lie between the Caspian Sea and the Black Sea NDA 2020 — the Caucasus separates the Caspian and Black Seas. |
| Panama Canal | Links the Atlantic and Pacific Oceans NDA 2020 — Panama joins the Atlantic to the Pacific. |
| New Zealand | Part of Polynesia |
| Adelaide | Known for viticulture (wine) |
Global organisations and environmental conventions4 rows
| Topic | Fact |
|---|---|
| WMO headquarters | Geneva NDA 2017 — the World Meteorological Organization is in Geneva. |
| Cartagena Protocol (2000) | Biosafety, under the Convention on Biological Diversity NDA 2020 — the Biosafety Protocol is the Cartagena Protocol. |
| Eastern Canada issue | Acid precipitation |
| Biosphere Reserve idea | UNESCO, 1973–74 NDA 2020 — true: UNESCO 1973–74; false: 'all Indian reserves are in the UNESCO network'. |
Watch out for (2)
- Driest is not the same as biggest→ World deserts and country nicknames
- 'All Indian Biosphere Reserves are in the UNESCO network' is FALSE→ Global organisations and environmental conventions
