What was the appearance of the primitive earth? What changes must have taken place that resulted in the earth we know today? These are some of the questions that scientists have been addressing for years. There has been much speculation about the structural origins of the earth. The most thought-provoking being the idea that at one stage in the earth’s history all the continents were joined together to form a single mass of land.
