World Geography – SSC JE Study Notes
Subject: General Awareness & Current Affairs
1. Simple Explanation
World geography is the study of the Earth’s physical features (continents, oceans, mountains, rivers, climate zones) and the human-made patterns that shape it (countries, capitals, time‑zones, population distribution, economic regions). For the SSC JE exam, you need to know:
- The seven continents and the five oceans.
- The major countries by area, population, and GDP.
- Capitals and key cities.
- Rivers and mountain ranges that define borders.
- Climate zones and their significance.
- Time‑zones and time‑difference facts.
- Recent current‑affairs changes (new capitals, borders, geopolitical events).
The goal is to recognise a country or a geographic feature from a short description during the exam.
