If It's Neither, How Were South America's Table Mountains Formed? — Highlights

Tepuis in Numbers — South America's Table Mountains: 979m·1.8 Billion Years·1.8 Million Years

A 30-second vertical highlight built only from figures in the original. It opens with Angel Falls, the world's tallest at 979m, then covers Mount Roraima at 2,810m above sea level, more than 100 tepuis, mountains left behind when a plateau eroded about 1.8 billion years ago, a hard summit of over 95% quartz, a 2.2cm toad, and a divergence just 1.8 million years ago.
