World Atlas — Continents & Oceans [EPUB ebook] 

Africa, the Americas, Antarctica, Asia, Australia together with Oceania, and Europe are considered to be Continents.
The term continent is used to differentiate between the various large areas of the earth into which the land surface is divided. So, a continent is ‘a large, continuous area of land on Earth’. All continents together constitute less than one-third of the earth’s surface, that means more than two-thirds of the earth’s surface are covered with water.
The book contains outstanding maps that help children learn the continents and oceans of the world.
