Deltaic deposits
Magnetic delta deposits

Each piece of S-shaped card represents the sediments from platform to prodelta laid down
in each unit of time. Once all the five pieces have been put on the board the coarsening
upward sequence becomes obvious. It can also be used to show diachronous beds and
Walther's Law.

As above but students are given the pieces of paper and must stick them in position and

Delta switching

Make overhead transparencies of each of the most important historic deltas and of the
present coastline of the Mississippi. Lay them one by one on top of each other to show how
the delta has changed position.
