Question

the energy of a wave moves sand down a beach along with the wave. this phenomenon is known as what? select choice rip currents longshore transport standing waves tsunamis progressive wind waves

Explanation:

• Longshore transport: It is the movement of sediment (like sand) along a beach by the action of waves. Waves approach the shore at an angle, and this causes a current (longshore current) which moves the sand along the beach.
• Rip currents: These are narrow, fast - moving currents of water that flow away from the shore. They are not related to the movement of sand along the beach with the wave energy.
• Standing waves: These are waves that do not appear to move horizontally. They have points (nodes) that do not move and points (antinodes) of maximum amplitude. They are not involved in the transport of sand along a beach.
• Tsunamis: These are large ocean waves usually caused by underwater earthquakes, volcanic eruptions, or landslides. They are not about the movement of sand along a beach due to regular wave action.
• Progressive wind waves: These are waves that are generated by the wind and move in the direction of the wind. While wind is involved in wave generation, the specific term for the movement of sand along the beach with wave energy is longshore transport.

Answer:

longshore transport
