National Geographic Travelさんのインスタグラム写真 - (National Geographic TravelInstagram)「Photo by @daisygilardini | Icebergs in Antarctica are simply breathtaking. They form when ice calves from glaciers. Over time wind, rain, and sea erosion sculpts and reshapes the ice into unique and dramatic forms. Icebergs will roll over several times during their lifetimes. What was once underwater is exposed on the surface. This iceberg probably flipped upside down recently, as you can still see the stripes caused by the air bubbles released from the ice while underwater.
