My class has been working on an erosion projects. Before and after an erosion. My group was Jarod, Sydney, and me. We had wave erosions. There are y types of erosion. Water erosion, wave erosion, glacier erosion, and wind erosion. Our vocab words were, Wave refraction, Estuary, Longshore bar, Longshore current, Barrier Island, Baymouth bar, and Sea cave. My favorite vocab words areWave refractions and Sea cave. A wave refraction is when waves change directions, passing from one spot to another. A sea cave is a cave created by wave erosion on the side of an island or rock.
