UPSC Prelims 2010 Q96: Geography – Atmosphere & Climatology
A geographic region has the following distinct characteristics:
1. Warm and dry climate
2. Mild and wet winter
3. Evergreen oak trees
The above features are the distinct characteristics
of which one of the following regions?
- (a) Mediterranean
- (b) Eastern China
- (c) Central Asia
- (d) Atlantic coast of North America
Answer: (a) Mediterranean
Explanation
Identifying a climate region from three distinct clues
The clues — warm/dry climate, mild/wet winters, evergreen oak trees — point to a well-known climate type.
| Option | Verdict | Reason |
|---|---|---|
| (a) Mediterranean | Correct | The Mediterranean climate is specifically characterized by hot, dry summers and mild, wet winters, with vegetation like evergreen oaks (classic Mediterranean scrub/woodland) |
| (b) Eastern China | Incorrect | Eastern China has a humid subtropical/monsoon climate pattern, not this specific summer-dry/winter-wet combination |
| (c) Central Asia | Incorrect | Central Asia is largely continental and arid, without this specific wet-winter pattern |
| (d) Atlantic coast of North America | Incorrect | This region has a different, generally more humid year-round climate pattern, not the Mediterranean's distinct dry-summer/wet-winter cycle |
Mediterranean climate signature:
| Point | Detail |
|---|---|
| Summer | Warm and dry |
| Winter | Mild and wet |
| Vegetation | Evergreen oak and scrub (Mediterranean woodland) |
Answer: (a) Mediterranean.
Why each option is right or wrong
- (a) CORRECT. Warm, dry summers; mild, wet winters; evergreen oaks — this is the textbook Mediterranean climate signature.
- (b) Incorrect. Eastern China's monsoon-driven climate doesn't match this specific dry-summer/wet-winter pattern.
- (c) Incorrect. Central Asia's largely arid, continental climate doesn't fit this wet-winter description.
- (d) Incorrect. The Atlantic coast of North America has a different, more evenly humid climate pattern.
Key point
Warm/dry summers + mild/wet winters + evergreen oak trees = the classic MEDITERRANEAN climate signature, distinct from the monsoon, continental, or humid Atlantic-coast patterns of the other options.
Remember
Warm/dry summer, mild/wet winter, evergreen oak trees: the Mediterranean climate's signature combination.
Common mistakes
- Confusing the Mediterranean's dry-summer/wet-winter pattern with monsoon or continental climate types.
- Not connecting evergreen oak vegetation specifically to the Mediterranean biome.
- Assuming any coastal region shares the same seasonal rainfall pattern as the Mediterranean.
Exam tip
Mediterranean climate = dry summer + wet winter + evergreen oak/scrub. A distinctive, frequently tested climate-type signature.
