World Geography
Overview
World Geography forms an essential part of the Social Studies section in WB TET Paper II. Questions typically test your knowledge of continents, oceans, major physical features and important countries. This topic connects directly with understanding global patterns of climate, landforms and human settlement — concepts that upper-primary students must learn.
For the exam, focus on factual recall: names, locations, superlatives (largest, longest, highest) and basic physical characteristics. Map-based mental visualisation helps immensely. This topic often overlaps with questions on Indian geography, so understanding India's position in the global context is valuable.
Expect 3–5 questions on world geography. Mastery requires memorising key facts and being able to distinguish between similar-sounding features (e.g., which mountain range is in which continent).

Key Concepts
- **Seven Continents**: Asia, Africa, North America, South America, Antarctica, Europe and Australia/Oceania — arranged from largest to smallest by area.
- **Five Oceans**: Pacific (largest), Atlantic, Indian, Southern (Antarctic) and Arctic (smallest) — together covering about 71% of Earth's surface.
- **Latitude and Longitude Grid**: Equator (0° latitude) divides Earth into Northern and Southern Hemispheres; Prime Meridian (0° longitude) divides into Eastern and Western Hemispheres.
- **Major Landforms**: Mountains, plateaus, plains, deserts, islands and peninsulas are the primary physical features tested.
- **Ring of Fire**: A horseshoe-shaped zone around the Pacific Ocean where most earthquakes and volcanic eruptions occur.
- **Continental Drift**: The theory that continents were once joined (Pangaea) and have drifted apart — explains why coastlines of Africa and South America fit together.
- **Climate Zones**: Tropical, temperate and polar zones based on latitude; equatorial regions are hottest, poles are coldest.

Key Facts
### Continents — Essential Data
| Continent | Area Rank | Key Feature | Largest Country | |-----------|-----------|-------------|-----------------| | Asia | 1st (largest) | Highest peak — Mt Everest (8,849 m) | Russia (by area) | | Africa | 2nd | Longest river — Nile (6,650 km) | Algeria | | North America | 3rd | Grand Canyon, Great Lakes | Canada | | South America | 4th | Amazon rainforest, Andes mountains | Brazil | | Antarctica | 5th | Coldest, driest, no permanent population | — | | Europe | 6th | Most industrialised, densest population | Russia (partly) | | Australia | 7th (smallest) | Great Barrier Reef | Australia |
### Oceans — Essential Data
| Ocean | Area Rank | Key Fact | |-------|-----------|----------| | Pacific | 1st (largest) | Mariana Trench — deepest point on Earth (11,034 m) | | Atlantic | 2nd | Busiest ocean for trade routes | | Indian | 3rd | Warmest ocean | | Southern | 4th | Surrounds Antarctica | | Arctic | 5th (smallest) | Mostly frozen, surrounds North Pole |
### Important Physical Features
- **Highest Mountain**: Mt Everest (Nepal-Tibet border) — 8,849 m
- **Longest River**: Nile (Africa) — 6,650 km; Amazon is second — 6,400 km
- **Largest Lake**: Caspian Sea (saltwater); Lake Superior (freshwater)
- **Largest Desert**: Sahara (hot desert); Antarctica (cold desert, technically largest)
- **Longest Mountain Range**: Andes (South America) — 7,000 km
- **Largest Island**: Greenland
- **Largest Plateau**: Tibetan Plateau (Roof of the World)
### Important Countries and Capitals
| Country | Capital | Notable Fact | |---------|---------|--------------| | Russia | Moscow | Largest country by area | | Canada | Ottawa | Second largest country | | China | Beijing | Most populous country | | USA | Washington D.C. | Third largest by area | | Brazil | Brasilia | Largest in South America | | Australia | Canberra | Only country that is also a continent | | Egypt | Cairo | Gift of the Nile |

Worked Examples
### Example 1: Identifying Continents and Features
**Question**: Which continent has both the Amazon River and the Andes Mountains?
**Solution**:
- Amazon River flows through Brazil, Peru and other countries
- Andes Mountains run along the western coast
- Both features are in South America
**Answer**: South America
---
### Example 2: Ocean-Related Question
**Question**: The Mariana Trench, the deepest point on Earth, is located in which ocean?
**Solution**:
- The Mariana Trench is near the Mariana Islands
- It lies in the western Pacific Ocean
- Depth: approximately 11,034 metres (Challenger Deep)
**Answer**: Pacific Ocean
---
### Example 3: Comparative Geography
**Question**: Arrange these rivers in order of length (longest first): Ganga, Nile, Amazon, Yangtze
**Solution**:
- Nile: 6,650 km (longest)
- Amazon: 6,400 km
- Yangtze: 6,300 km
- Ganga: 2,525 km
**Answer**: Nile → Amazon → Yangtze → Ganga

Common Mistakes
**Confusing Nile and Amazon lengths** → The Nile is generally accepted as the longest river (6,650 km). Some measurements place Amazon longer, but for exams, remember Nile as longest.
**Mixing up Arctic and Antarctic** → Arctic is the northern polar region (ocean surrounded by land); Antarctic/Antarctica is the southern polar region (land surrounded by ocean). Memory trick: Arctic has "c" for "cap" at top; Antarctic has "ant" — ants on the bottom.
**Forgetting that Australia is both a country and a continent** → When asked about the smallest continent, the answer is Australia (or Oceania), not Europe.
**Assuming Sahara is the largest desert** → Sahara is the largest hot desert. Antarctica is technically the largest desert (receives very little precipitation). Read questions carefully.
**Confusing Greenland and Australia** → Greenland is the largest island; Australia is a continent, not an island.
**Placing Andes in wrong continent** → Andes are in South America (western edge). Rockies are in North America. Alps are in Europe. Himalayas are in Asia.

Quick Reference
- **7 Continents (size order)**: Asia → Africa → North America → South America → Antarctica → Europe → Australia
- **5 Oceans (size order)**: Pacific → Atlantic → Indian → Southern → Arctic
- **Superlatives**: Everest (highest), Nile (longest river), Caspian Sea (largest lake), Sahara (largest hot desert), Pacific (largest ocean), Mariana Trench (deepest point)
- **Ring of Fire**: Pacific Ocean edges — zone of earthquakes and volcanoes
- **Equator passes through**: Ecuador, Colombia, Brazil, Gabon, Congo, Uganda, Kenya, Somalia, Maldives, Indonesia
- **Prime Meridian (0°)**: Passes through Greenwich, London — divides Eastern and Western Hemispheres
