Which of the following is the most effective agent of coastal erosion?
Answer Details
Sea waves are the most effective agent of coastal erosion. This is because waves carry a lot of energy and force, which can cause rocks and other materials on the coast to break down over time. As waves approach the shore, they slow down and become taller, causing them to crash onto the beach with more force. This force can cause erosion by breaking down rocks and carrying sediment away from the coast. Sea currents, underground water, and sea tides can also contribute to coastal erosion, but waves are generally considered to be the most significant factor.
