Students were investigating the effect of wind direction on longshore drift on part of the Holderness coast. Longshore drift is the movement of material along a coastline due to the angled approach of waves.
They were testing the hypothesis that ‘Sediment size will decrease in the direction of the strongest winds.’
The students calculated the mean sediment size on the beach in four locations on the Holderness coast. The map below shows the primary data collected by the students at the four locations.
The students used secondary data to discover wind directions on the Holderness coast over the last five years.
Use the primary and secondary data collected by the students to write a conclusion to their investigation that ‘Sediment size will decrease in the direction of the strongest winds.’
