can cause sand buildup on updrift ide of structure

1. Jetty: Hard structure Built Perpendicular to the Shore, Can cause sand build-up on up drift side of the structure

2. Beach Nourishment: Brings in more sand to replace erosion.

3. Seawall: Hard structure that also provides flood protection, Prevents erosion by directing waves back to the ocean

Explanation:

Jetty is a hard and long structure that constructs of wood or concrete near the coastline, perpendicular to the shore that protects it from tides and currents which helps in preventing erosion. It can lead to build-up of sand on updrift side.

Beach nourishment is the process that replaces the sand or land that lost due to erosion and relensihsh the infrastructure of the coastline and protects the people and beach.

Seawall is also a hard provides protection from erosion by preventing the flood and pushes back the currents and tides to the ocean.

a=c and then d= c because of the band so you get ac/dc and you add them together you get sound waves

for a different answer set the answer would be because the oxygen in the water had depleted (apex)
