Sole marks - sedimentary structures

The new ELI today continues our sedimentary structures series with 'Sole marks - evidence from the base of a sedimentary bed'. This activity is based on diagrams and photographs of sole marks, where pupils are asked to look for evidence of past environments and the orientation of the samples.
Many more exciting and stimulating ideas for teaching Earth science or geography can be found on our website.

A good exercise, but there is an implication in the text that these sole structures are found only on the bases of turbidites. Individual sedimentary structures tell us about processes, not environments. Some of the best flutes and grooves I have seen are on the bases of fluvial channels.

Following the helpful comment from Roger, the activity is under review and will be re-published shortly.
