It may not be practical to physically land on different planets
It is possible to use trigonometry to determine terrain features
This is done by using the position of the sun and the length of the shadows cast by different objects

Pupils may not be convinced that a right angled triangle is formed.

For the model, we assume that the terrain feature is perpendicular to the surface.
