This, Jakobshavn Isbrae, is the fastest flowing glacier 1 on our planet, moving as much as 14 meters a day. As it advances, it destroys everything in its path, even cutting its way through Greenland's great mountain ranges on its drive downwards 2 towards the sea.
When speeded up, these solid rivers of ice seem to flow, just like liquid rivers.
This is the titanic 3 force that cuts down mountains and levels the surface of continents.
The ice is now entering the last stage of its descent. As it gains speed, huge crevasses 4 open that extend out to its very core. It’s reached the ocean and millions of tons of ice have lost the support of their rocky bed. Something must give. These ice falls are an ominous 5 sign of what is about to happen, a rupture 6 deep within the glacier.
