about 250 million years ago the dry land of the world consisted of one large continent known as Gondwanaland. This continent floated on a lake ofliquid that is the core of the earth weaknesses in Gondwanaland led to cracks forming resulting in the formation of shields that now comprise the continents of the Earth. These began to break away from each other 250 million years ago leading to the position of the continents as we know them today. Australia was one of these Shields and broke free from what is Asia today about 30 million years ago.
