What is the name for strong flows that move away from the shore and can carry sediments offshore?

• A. Jetties
• B. Backwash
• C. Rip Currents
• D. Groins

Answer: (C)

Rip currents are strong, narrow channels of water that surge seaward through the surf zone. They move away from the shore, and their powerful flow can carry suspended sand and other sediments offshore, reshaping the beach where they occur. This seaward, concentrated current is what makes them the correct term for the described phenomenon. Jetties and groins are man-made structures that alter sediment movement and protect harbors, but they don’t describe a continuous flow pulling water and sediment away from the beach. Backwash is the water returning to the sea after waves break, not the sustained offshore current that carries sediments away.
