Wall Element - Earth

Earth is the only planet known to have ongoing geological activity, such as earthquakes and volcanoes. It is the only planet known to have life.

Earth has one natural satellite, the Moon, which is the only large satellite of a terrestrial planet in the Solar System. This learning board demonstrates how the Moon orbits Earth and how Earth orbits the Sun. It also explains why we have day and night, as well as why there are four seasons in a year.

The learning also shows the inner structure of the Earth and demonstrates what happens inside a volcano when it erupts. Special lighting effects are used to enhance the demonstration of orbiting and volcanic eruptions.
