- 1勞亞古陸（北方古大陸；南邊那塊是岡瓦納大陸 Gondwana）
Laurasia is the name give to the great northern of the ancient world. The story goes like this: about 300 million years ago nearly all land on Earth was joined in one supercontinent, . Around 200 million years ago began to split, and it split into two — Laurasia in the north and Gondwana (or ) in the south. Laurasia later broke apart again into what we now call North America, Europe, and most of Asia, plus . So when scientists explain why the same kinds of old fossils turn up in Canada and in Scotland, Laurasia is the answer: those places were once one piece of ground. It is a proper noun, so it always takes a capital L, and it takes no "the" — you say "Laurasia broke apart", not "the Laurasia". The word belongs to geology, geography, and school science; it is not an everyday word, but any student reading about dinosaurs or continental drift will meet it.
組成A blend of two names: Lauren(tia) + (Eur)asia. Laurentia is the geologists' name for the ancient core of North America — named after the St Lawrence River region in Canada — and Eurasia is Europe plus Asia. So the name literally packs together the two halves of what the continent became.
