1. Simple Explanation
World geography is the study of the Earth's physical and human features that shape global interactions.
- Physical Geography – landforms (mountains, plains, deserts), bodies of water (oceans, seas, rivers), climate zones, and natural resources.
- Human Geography – countries, capitals, population distribution, languages, religions, economic activities, and international organizations.
For the TET exam, focus on the basic facts that are asked in multiple-choice questions – e.g., which continent has the largest population, what are the five oceans, what is the longest river in the world, etc.
