World Geography – Study Notes (UPTET General Awareness & Current Affairs)
1. Simple Explanation
World geography is the study of the Earth's physical features, human settlements, and how they interact. For UPTET, focus on:
- Physical geography – continents, oceans, major mountain ranges, rivers, deserts, climate zones, and natural resources.
- Human geography – countries, capitals, major cities, population distribution, languages, religions, and economic zones.
- Geopolitical units – sovereign states, territories, dependent areas, and special regions.
- Time & Space – time zones, longitudinal/latitudinal coordinates, and the concept of “world regions” used in international cooperation.

| Mountain Ranges | Himalayas, Andes, Alps, Rockies, Atlas, Ural | Highest peak: Mount Everest (8,848 m). |
| Major Rivers | Nile, Amazon, Yangtze, Mississippi, Ganges | Amazon is the longest in terms of discharge. |
| Deserts | Sahara, Arabian, Gobi, Kalahari, Antarctic | Sahara = 9.2 M km². |
| Climate Zones | Tropical, Arid, Temperate, Continental, Polar | Köppen climate classification. |
| Time Zones | 24 primary zones + 40+ half‑hour & 45‑minute variations | IST = UTC+5:30. |
| World Regions (UN) | Africa, Americas, Asia, Europe, Oceania | UN’s 5 regions used for statistical reporting. |
| Country‑Capital Pairs | 195 UN member states + 2 observer states | Japan – Tokyo, Brazil – Brasília. |

| Geopolitical Units | Sovereign state, dependent territory, special administrative region | Hong Kong SAR, Puerto Rico (USA). |
| Important Maps | Political map, physical map, topographic map, climate map | Political map shows borders; physical shows terrain. |
| Coordinates | Latitude (North/South), Longitude (East/West) | Delhi: 28.61° N, 77.23° E. |
| World Heritage Sites | UNESCO list > 1,000 sites | Taj Mahal, Great Barrier Reef. |
3. Worked Example
Question: If a student in New Delhi (IST, UTC+5:30) calls a colleague in London (GMT, UTC+0) at 3:00 PM Delhi time, what is the local time in London?
Solution Steps
-
Convert Delhi time to UTC
- Delhi time = 15:00 (3:00 PM)
- UTC = Delhi time − 5 h 30 m
- UTC = 15:00 − 5:30 = 09:30 UTC
-
Convert UTC to London time
- London (GMT) = UTC + 0
- London time = 09:30
Answer: The colleague in London will see the call at 9:30 AM.
