Load casts - sedimentary structures

The latest ELI continues the sedimentary structures series with 'Load casts; interpreting odd bumps on the bases of beds'. This activity is based on photographs and diagrams of load casts. Pupils are asked to interpret how the structures formed and therefore to infer past environments. They can model load casts with sand and water as shown in the photo above.
The other activities in the sedimentary structures series can be found in 'related activities' on our website.
