Meteorites are dark coloured lumps of rock that fall from space to earth. They can be very small but on a continent covered in snow and ice, it’s easy to see them.

The puzzle has come about because it seems some meteorites hit the surface then melt down into the ice before slowly ‘floating’ up to the surface again some time later.
