Final answer:
Beach material is moved through wave action, erosion, ocean upwelling, and turbidite sedimentary processes, which can be evidenced by sediment features such as cross-bedding.
Step-by-step explanation:
The transportation processes that move material down the beach include wave action, which transports sediment containing well-sorted gravel and sand. This process occurs along coastlines with high energy, such as at Island Beach State Park in New Jersey. Additionally, erosion shapes the earth's surface by weath-ering and transporting fragments of rock and sediments.
Furthermore, ocean upwelling is an important process that involves the movement of nutrient-rich deep ocean waters to the surface, which can also carry sediments along with the nutrients. Turbidite sedimentary deposits on the sea-bottom formed by slope failures result in currents carrying grains sorted by density. Cross-bedding in sedimentary rocks is evidence of past sediment transportation by wind or water, where geologists can determine the direction of the transport.
