| From Classbrain.com Geology This interactive geological timeline of the Earth from the BBC helps the past to come alive. This excellent presentation on the changes that have occured to earth through the ages condenses the separation of the continents, and the recurring ice ages into a matter of seconds. It's fascinating to watch as the polar ice caps reach down into the United States, only to retreat once again to the most minimal coverage. This is also a wonderful exploration of the Earth's land form shift. Flash is required to view this presentation. If you cannot see the presentation, you must update your Flash player.
