This 90-minute documentary explains the geological and biological history of Earth, from its formation 4.5 billion years ago to the present day. Explained are the very beginnings of the Earth; the formation of the crust and atmosphere; the origins of water; when life began in the oceans and moved to the land; the Carboniferous period and how it ended; when dinosaurs ruled the land and the arrival of mammals; and the numerous ice ages. The documentary also explains plate tectonics and ends with the foreseeable next stages of our planet until its final stagnation about 2 billion years in the future.
