History Documentaries
🌍 Six continents separated by vast expanses of water – this is the familiar image of our planet that we have all shared since childhood. But the Earth hasn’t always looked like this. Over the past 4.6 billion years, our planet has gone through many geological eras. During some of these eras, almost the entire surface was covered with ice, while in other periods, on the contrary, the polar caps melted completely.
