The World's Building Blocks
Continents are the biggest building blocks people use to describe the shape of the world. A continent is defined as a large unbroken landmass completely surrounded by water, although in some cases continents are (or were in part) connected by land bridges. The seven continents are usually given as North America, South America, Europe, Asia, Africa, Australia, and Antarctica.

Political considerations have often overridden geographical facts when it came to naming continents. Geographically, Europe, including the British Isles, is a large western peninsula of the continent of Asia; and many geographers, when referring to Europe and Asia, speak of the Eurasian continent. Because of that, there are many different competing models of the continents.
