What the world looks like naked: The amazing image of Earth's geology laid bare

This amazing image reveals what our world looks like when it is stripped bare - shorn  of all its plants, topsoil, water and man-made structures.

Along with other never-seen-before images of the Earth, the picture has been unveiled at OneGeology  - the world's biggest ever geological mapping project.

Scientists behind the project hope it will to do for the ground beneath our feet what Google has done for the Earth's surface with its Google Maps, Earth and Street utilities.
