Globes are the only representation of the earth that can accurately depict the land masses, bodies of water, borders and geographical locations. Flat maps distort the area they are meant to represent, with the distortion growing more the larger the represented area. The circumference of the Earth is quite close to 40 million metres. Many globes are made with a circumference of one metre, so they are models of the Earth at a scale of 1:40 million. The sphericity of the Earth was first established by the Ancient Greeks in 3 BC, this is when the first spherical globe appeared. Traditionally, globes were made from paper maps glued to a wooden sphere, although these days most globes are made of thermoplastic. Thanks so much for getting this fun globe tattoo from me Lauren!
