Did you know that Icebergs in the Antarctic area sometimes have stripes!? They are formed due to layers of snow that react to different conditions.


When an iceberg falls into the sea, a layer of salty seawater can freeze to the underside. If this is rich in algae, it can form a green stripe.


Blue stripes are often created when a crevice in the ice sheet fills up with melt water and freezes so quickly that no bubbles form.



Brown, black and yellow lines are caused by sediment, picked up when the ice sheet grinds downhill towards the sea.
