Longshore drift occurs on beaches where prevailing winds create waves that approach the shore at an angle, moving sand along the coastline. Factors such as the orientation of the beach, the strength and direction of the waves, and the presence of obstacles like jetties or groins can influence this process. Conversely, beaches sheltered from strong wave action or with a perpendicular shoreline may experience minimal or no longshore drift. Additionally, variations in sediment supply and local currents also play a significant role in the occurrence of longshore drift.
Longshore drift or laminar flow occurs along beachs where the surf comes in at a horizontal angle to the beach. If the beach runs North-South, and the waves come in from the Southwest, you're likely to experience longshore drift to the North.

Longshore drift generally occurs when waves approach the shoreline at an angle, creating a zig-zag pattern of sediment transport along the coast. This process is most common in areas with strong wave action and prevailing currents that move sediment along the shore.
Beach drift occurs due to the movement of sand particles along the shoreline. It is mainly driven by wave action, which pushes sand particles in a zigzag pattern along the coast. This process helps to shape beaches and distribute sediment along the shoreline.

Small populations
Genetic drift has a larger effect on smaller populations.
On the beaches of Normandy, western France.
Genetic drift is more likely to occur in small populations where chance plays a significant role in determining the frequency of alleles. It can also happen in isolated populations or during population bottlenecks where genetic diversity is reduced.
False. Genetic drift is more likely to occur in small populations where chance events can have a greater impact on allele frequencies. In large populations, genetic drift is typically less influential compared to other evolutionary forces.
