Meet the Earth’s Giant Ice-Carved Valleys Filled With Ocean Water!

These super-deep, dramatic ocean valleys are called fjords, and they were carved out by giant, slow-moving rivers of ice called glaciers thousands of years ago! When the heavy ice melted, the sea rushed in to fill these giant pathways, creating some of the most beautiful and steep water cliffs on our planet. Imagine sailing on a boat with mountain walls towering so high above you that they touch the clouds!
