A three-dimensional display assembly conveying Earth science information. In the current bottom, the display assembly is a series of interconnected inset spherical layers which represent the inner and outer layers of the Earth. The layers are constructed of in the current embodiment, a foam like material which provides for ease construction and displaying various Earth information such as geographic information, rock formations landmasses etc. On the outer surface of the Earth's crust, the continents and oceans are represented in graphical format by imprinting images on series of polyvinyl chloride sheeting which configures to the curvature of the sphere. The inner spheres are accessible to look into the various layers of the Earth by taking the top hemisphere of the outermost layer off. This is done by removing a securing device which in the current bottom is a latch laid flush with the top surface of the sphere.
