Amazing Geological Features of Earth
The Earth is defined by seemingly endless examples of stunningly amazing geological features. Try to imagine the full-body rush of plunging 148 feet beneath ice cold Icelandic glaciers to swim between tectonic plates separating two continents. Or taking a selfie atop 29,029 feet of the glorious Mount Everest. Or wouldn't it be great if you'd been there 6 million years ago to Instagram the exact moment when the Colorado River began to erode limestone that would eventually carve out the Grand Canyon? The wold is full of stunningly beautiful geological anomalies like these. Even the world's tallest, most pristine skyscrapers would be hard-pressed to hold a candle to Earth's natural, awe-inspiring wonders.
So where exactly are these significant structures? What led to their formation and what do they tell us about the age of the earth itself? To find out, grab your atlas, hiking gear, wetsuit and flashlight and explore all corners of the world through this playlist.
