Striped Ice
The world is truly an amazing artist.
The photographs here are of striped icebergs. They are formed by layers of snow that react to different conditions.
The blue stripes can be created when a crevice in the ice opens up, fills with melt-water and then freezes so quickly no air bubbles form.
When glaciers or icebergs calve, the piece falls into the sea, trapping salt water that may be rich in algae underneath. This can produce a green stripe.
Brown, black and yellow rifts are caused by glaciers that have pushed their way across the ground to the sea, collecting different sediments.
Amazing!
