Icebergs with colored strips. God's
wonderful creation AGAIN
Amazing striped icebergs
Icebergs in the Antarctic area sometimes have
stripes, formed by
layers of snow that react to
different conditions.
Blue stripes are often
created when a crevice in the ice sheet
fills up
with meltwater and freezes so quickly that no bubbles
form.
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.
Brown, black and yellow
lines are caused by sediment, picked up
when the
ice sheet grinds downhill towards the
sea.
