About this app
In this simulation, you will be given a holoprojector which will allow you to observe the six layers of the Earth and measure their properties, including depth, temperature, density and pressure. You will also be able to observe the five layers of the atmosphere. The simulation recreates the planet Earth with a cross-section showing the different layers, and you can click on each one in order to obtain an enlarged view.
