There are many interesting displays of ice around the world. One that especially caught my eye were the striped icebergs of Antarctica. When we think of icebergs, we think of white ice sculptures in the middle of the ocean. But these icebergs can be many different colors such as green, blue, black, yellow, and brown. Blue ice appears when water slides in the cracks of the iceberg and freezes so fast that no bubbles are formed. Green ice forms from water that freezes and contains algae. Black, yellow, and brown stripes form from sediments accumulated when the ice is sliding down.
There are also pink icebergs that form due to the growth of algae inside the ice. When this algae is effected by UV rays, a reddish pink color is shown. This is so fascinating to me, I never knew an iceberg could be so many different colors!
