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.
Continental Drift
long-shore drift
Till and stratified drift :D Did you get this from Portola MS in 6th grade workbook for Science?
Continental Drift is causing the continents to move around.
effect. longshore drift is the combined effect of sediments moved by longshore currents and and beach drift. longshore currents are ocean currents that flow parallel to the coast while beach drift is the resultant zigzag movement along the beach.

Small populations
Genetic drift has a larger effect on smaller populations.
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.
genetic drift, mutation, natural selection, and migration
Genetic drift may occur when a small group of individuals colonizes a new habitat. These individuals may carry alleles in different relative frequencies than did the larger population from which they came.
natural selection or genetic 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.

The condition necessary for genetic drift to have a significant effect on a population is when the population size is small. In smaller populations, genetic drift can lead to random changes in allele frequencies, impacting the overall genetic diversity of the population.
Genetic drift is most likely to occur in small populations where random events can have a greater impact on allele frequencies. It is also more common in isolated populations with limited gene flow from other populations.
