Geological mapwork continued

The latest ELI is the second in our geological mapwork from scratch series; 'valley with simple geology - draw your own cross sections and geological 3D model'
Pupils are shown a photograph of a straight valley, a simple landform. They are given a very simple geological map of such a landform, with
horizontal beds. They are asked to draw topographical cross sections of the valley, adding the geology to produce geological cross sections.
As the cross-section drawing progresses, it involves more interpolation and more three-dimensional thinking skills. Pupils will realise that all the geological boundaries and therefore all the beds are horizontal. This will allow them to complete the 3D block diagram successfully.
Many more investigative activities can be found on our website.
