The Continents

The most common view held today identifies seven continents. These seven landmasses are shown below.

  • Asia
  • Africa
  • Antarctica (not displayed on the map)
  • Australia (part of Oceania on the map)
  • Europe
  • North America
  • South America

Sometimes, Europe and Asia are combined into one continent known as Eurasia. This results in only six continents.

Comparison of Continents

The size of each continent is shown in the chart below. Continental size is shown in the millions of square kilometers. Asia is the largest continent. Australia is the smallest continent.

Asia 43.8 million sq. kilometers
Africa 30.4 million sq. kilometers
North America 24.5 million sq. kilometers
South America 17.8 million sq. kilometers
Antarctica 13.7 million sq. kilometers
Europe 10.2 million sq. kilometers
Australia 9.1 million sq. kilometers

Geology of a Continent

A continent is part of the earth’s crust. It is made up of a lighter material than the ocean floor. A continent is part of a large tectonic plate that is moving slowly. These tectonic plates often collide. The collision of two plates create smaller landforms such as mountains and ocean trenches.

Population and the Continents

The population of a continent is related to its size. Asia and Africa have the largest populations. Today, over 4 billion people live in Asia.  Africa has the second largest population with slightly more than 1 billion people. Antarctica and Australia have the smallest populations.

Asia and Europe are the most densely populated countries. Antarctica and Australia have the lowest population densities.
