It is not possible to reflect the surface of a sphere (3D) in a plane (2D) in a completely "real way" (a 'projection' method is needed).
True
False
True or false: Globes provide a three-dimensional view of the Earth. They provide the most accurate view of the world, but have limitations in their use.
True
False
True or false: Globes show more detail and are easier to transport than maps are.
True
