BharatNotes Pangaea
noun (proper noun)Usage in a UPSC answer
Just as the geological breakup of Pangaea reshaped the planet's surface over aeons, the unravelling of a once-monolithic global order into competing blocs compels India to recalibrate its foreign policy for a more fragmented, multipolar world.

Pangaean (adj); No standard derived forms; related: Gondwana (n), Laurasia (n)
Root
Greek pan (πᾶν) = all; gaia (γαῖα) = earth, land; coined by Alfred Wegener in 1912
Etymology
From Greek pan (πᾶν, "all") + gaia (γαῖα, "earth, land"); coined by Alfred Wegener in 1912 to describe the hypothetical unified landmass from which the present continents drifted apart.
Memory Hook
PAN + GAEA = "all" + "earth" (Gaia, the Greek earth-goddess): Pangaea is the "all-earth" supercontinent where every landmass was once joined as one.
How This Word Works in UPSC Writing
The supercontinent from which today's landmasses separated. Alfred Wegener presented the idea publicly on 6 January 1912, and the shift he made is the examinable one: earlier explanations attributed the separation of continents to subsidence, whereas Wegener argued that the parts of Pangaea had moved thousands of miles laterally over geological time. Continental drift lacked a mechanism, and plate tectonics later supplied it, which is why the two should be presented as successive rather than as the same theory.
Don’t Confuse It With
Pangaea is the single supercontinent. Laurasia and Gondwana are the northern and southern masses into which it split. Panthalassa is the surrounding ocean, and Tethys the sea between Laurasia and Gondwana. Continental drift is Wegener's hypothesis; plate tectonics is the later theory that supplied the mechanism.
Hindi Meaning
पैंजिया (painjiyā), महाद्वीपीय विस्थापन being continental drift.
Common Questions
- What was Pangaea?
- The single supercontinent from which the present continents separated, proposed by Alfred Wegener, who presented the idea publicly in January 1912.
- How is continental drift different from plate tectonics?
- Continental drift described the movement but could not explain what drove it. Plate tectonics later supplied the mechanism through seafloor spreading and plate motion.
