The continent of Australia is not the same as the nation of Australia, which is only a part of the whole continent. The other parts of the continent include the island of New Guinea, as well as a number of smaller islands and the island state of Tasmania. In this book, travel across all these places, and on the way find out about ancient rocks, erupting volcanoes and unique animals. What is a continent, and are there seven or five? Some continents are surrounded by water, but others have borders with each other that are often difficult to define. Did you know that the continents can move? How does this happen and what does it mean for the future of the continent you live on? Find out all about Earth's continents, how they are similar and how they differ, as well as the effect people have had on the landscapes where they live.
