Consider the following pairs:

Sea Bordering country
1. Adriatic Sea Albania
2. Black Sea Croatia
3. Caspian Sea Kazakhstan
4. Mediterranean Sea Morocco
5. Red Sea Syria

Which of the pairs given above are correctly matched?

  1. A1, 2 and 4 only
  2. B1, 3 and 4 only
  3. C2 and 5 only
  4. D1, 2, 3, 4 and 5
Show answer

Answer: (B) 1, 3 and 4 only

The correct answer is (B) — 1, 3 and 4 only.

Pair 1 is correct — Albania borders the Adriatic Sea.

Pair 2 is wrong — Croatia borders the Adriatic Sea, NOT the Black Sea. The Black Sea is bordered by Turkey, Russia, Ukraine, Georgia, Romania, and Bulgaria.

Pair 3 is correct — Kazakhstan borders the Caspian Sea.

Pair 4 is correct — Morocco borders the Mediterranean Sea.

Pair 5 is wrong — Syria borders the Mediterranean Sea, NOT the Red Sea. The Red Sea is bordered by Saudi Arabia, Yemen, Egypt, Sudan, Eritrea, and Djibouti.

Tip:

  • Croatia = Adriatic (not Black Sea).
  • Syria = Mediterranean (not Red Sea).

These are the two tricky ones.

Why this was asked

World geography questions test knowledge of which countries border which seas - a fundamental skill for understanding global trade routes, regional conflicts, and economic zones.

The question creates confusion by pairing countries with seas they don't actually border - Croatia with Black Sea instead of Adriatic, and Syria with Red Sea instead of Mediterranean.

Students must memorize the exact coastlines of major seas to avoid these deliberate geographic mismatches that UPSC uses as traps.

Adriatic Sea & Bordering Countries

Geography Adriatic Sea Albania Croatia

Adriatic Sea: Location, Bordering Countries & UPSC Traps

Must know

Adriatic Sea is a subdivision of the Mediterranean Sea

Bordered by Italy (west) and Balkan countries (east)

Exam traps

Croatia borders Adriatic Sea, NOT Black Sea — UPSC frequently tests this confusion

Don't confuse Albania (Adriatic) with Bulgaria (Black Sea) — similar Balkan locations

Slovenia has only 46 km of Adriatic coast — shortest among bordering countries

Black Sea & Bordering Countries

Geography Black Sea Croatia

Black Sea: Bordering Countries & Strategic Importance

Must know

Good to know

Strategic importance for Russia's warm water access

Strategic Location

The Black Sea is an inland sea between Eastern Europe and Western Asia. It connects to the Mediterranean through Turkey's Bosporus and Dardanelles straits, making it Russia's key route to warm water ports.

Exam traps

Croatia borders Adriatic, NOT Black Sea — most frequent UPSC confusion about Black Sea

Don't mix up Georgia (Black Sea) with Albania (Adriatic) in Balkan geography

Turkey controls both straits (Bosporus & Dardanelles) connecting Black Sea to Mediterranean

Caspian Sea & Bordering Countries

All five countries (Russia, Kazakhstan, Iran, Azerbaijan, Turkmenistan) border Caspian — memorize this list

Mediterranean Sea & Bordering Countries

Geography Mediterranean Sea Morocco Syria

Exam traps

Syria borders Mediterranean, NOT Red Sea — Syria is in West Asia, far from Red Sea

Yemen and Djibouti control Bab el-Mandeb strait at Red Sea's southern entrance

Don't confuse Sudan (Red Sea) with South Sudan (landlocked after 2011 split)
