What is sand? What’s it made from, and how does it get from where it’s made to the beaches and sand dunes that surround many of our shores? On this album, Dr Dave McGarvie of The Open University takes us on a visit to Cornwall to follow grains of sand on their journey from the high moorland to the sea shore. Back in the lab, he demonstrates some techniques for looking in detail at samples of sand. The album draws on material originally created to support The Open University course Exploring Science.
Track 5: Transporting sand grains
Comparing the effectiveness of wind and water for moving sand grains of different sizes.
