Glacier calving is a natural event where large chunks of ice break off from a glacier. It's a visually stunning and powerful process. The waves created by calving have a strong impact on the water's surface. By watching a video of a glacier calving, we can better understand the magnitude and effects of this event. Glaciers are huge masses of ice found in the coldest regions of the Earth, formed by snow accumulating over thousands of years and slowly turning into ice.
