Whilst water is responsible for the deposition of the sediment, the concentration of larger pebbles results from deflation, a process associated with wind. Deflation occurs when winds blow across a bare desert surface selectively picking up fine sand and silt particles, leaving behind larger sediments to form a pebble-strewn desert pavement, or reg.

Activity: The Jam-Jar Experiment

Sand particles are the biggest and weigh more than silt - so the bottom layer will be the sand part of the soil. Any pebbles will also be at the bottom. Next up is the silt layer. Silt particles are smaller than sand and weigh less so they appear over the sand. If you were able to separate out any clay particles they are the smallest and will be on
