Long ago, about 200 million years back during the Jurassic period, huge lava flows created a flat basalt plateau. This rocky shelf stretched across the land where the Zambezi River flows today. For millions of years, the river wandered in different directions.
Around 2 million years ago, the land lifted up, changing the river's path. It started flowing straight toward a big crack in the basalt. About 20,000 years ago, the water poured over the edge, carving a deep gorge below called the Batoka Gorge. Today, the Zambezi plunges over this wide crack, 1,700 meters across, creating the amazing Victoria Falls. Two islands, like Livingstone Island, sit right on the edge during low water.
This slow process of uplift, cracking, and carving shaped one of the world's greatest waterfalls.
