Two hundred million years ago our Earth’s landscape looked nothing as we recognize it today. In this video, Professor Ron Blakely will demonstrate how the plant’s landscape changed overtime with the aid of a time-lapse animation. Millions of years ago, our planet comprised of a single huge continent which was surrounded by a majestic ocean. The change in this supercontinent stems from opening up of the Atlantic Ocean. Thereafter, the Earth’s forces, including earthquakes and tectonic movements, shaped the Earth’s landscape we know today.
