Today we divide the world into seven continents:
North America and South America are two

00:00:19.190 --> 00:00:27.480 align:middle line:84%
separate continents linked by an isthmus;
across the Atlantic Ocean sits Africa,

00:00:27.480 --> 00:00:37.750 align:middle line:84%
a large continent straddling the Equator;
separated from Africa by the Mediterranean Sea,

00:00:37.750 --> 00:00:44.610 align:middle line:84%
Europe is, in fact, a peninsula, extending
westward from the world's largest continent,

00:00:44.610 --> 00:00:56.020 align:middle line:84%
Asia; south of Asia lies Oceania, comprising
Australia and a large number of islands

00:00:56.020 --> 00:01:03.980 align:middle line:84%
in the Pacific Ocean; finally, the southern tip
of the planet is covered by the frozen ground

00:01:03.980 --> 00:01:08.100 align:middle line:90%
of Antarctica, the only uninhabited continent.
