解説 Definition
約3億年前から2億5000万年前に存在した、地球上のすべての陸地が一つに結合していた超大陸。現在の大陸分布の起源となった。
Pangaea was the supercontinent in which nearly all of Earth’s landmasses were joined before tectonic movement gradually separated them into the continents known today.
覚え方のコツ Memory Tip
pan-「すべて」と、地理を表す geography の geo- に近い gaia「大地」を結び、「すべての大地が一つ」という構成で覚える。Pangaea broke up「パンゲアが分裂した」、the supercontinent Pangaea「超大陸パンゲア」という地質学の表現とセットにするとよい。固有名詞なので通常は Pangaea と大文字で書く。
Break the name into pan-, meaning “all,” and a part connected with Greek Gaia, “Earth” or “land.” The structure therefore suggests “all the land,” an excellent image for a supercontinent containing nearly all major landmasses. Connect pan- with pandemic and the earth-related element with geography. In geology, remember it through common phrases such as the supercontinent Pangaea, the breakup of Pangaea, and the formation of the modern continents. Because it is a proper name, it is normally written with an initial capital: Pangaea.

pangaea の語源・成り立ち Etymology
ギリシャ語 pan（すべての）+ gaia（大地）から成る造語。1912年にドイツの気象学者ウェゲナーが大陸移動説で命名した超大陸。関連語: pandemic（pan+demos＝全民衆）、geography（geo+graphein＝大地を描く）。「すべてが一つの大地だった」という壮大な意味を持つ。
Pangaea was formed from Greek pan, meaning “all,” and Gaia or gê, meaning “Earth” or “land.” The name was adopted in the scientific discussion of continental drift associated with German scientist Alfred Wegener. Its components express the central idea directly: the continents were once united as essentially one great landmass. The spelling Pangea is also common, especially in American English, while Pangaea preserves the ae sequence.
