A continent is a historically long, continuous stretch of land. In total there are 7 continents: Europe, Africa, Asia, Australasia (Oceania), North America, South America and Antarctica.
Antarctica is known as the "White Continent"
Australia is known as the island continent because it is the only continent that is also a single country and is surrounded by water.
Africa.
Australia is not known as the "Dark Continent", that would be Africa.
Antarctica is known as the frozen continent.
Because it is known as a sub-continent, a part of Asia. In my view Europe and Asia should be one continent: Eurasia
It was known as the Dark Continent in the past.
Persia has been known as Iran since 1935 and it is located on the Asian continent.
The continent known as AFRICA.
The continent that does not have bees is known as Antarctica. This is the only continent that does not have what are known as insect-pollinated flowering plants.
Ur is the first known continent and existed 3 billion years ago.
Africa used to be known as the Dark Continent. This is because nothing was known about the interior of Africa up until about the mid 1800s. So to the outside world, interior Africa was known as dark and mysterious.
