Cape Cod was formed about 18,000 years ago when the glaciers started to melt, but how was it formed? It formed through a process called weathering and erosion. Weathering is the process of wearing away or changing the appearance or texture of (something) by long exposure to the water, wind, and even ice. Erosion is the process that takes the results of weathering away by water, wind, or other natural processes. The sediment was picked up by the glaciers and slowly eroded down towards Cape Cod. As the glaciers moved south, the warmer weather began to melt the glaciers and they dumped their load of sediment to form Cape Cod. In total, 3 glaciers formed Cape Cod. The middle lobe retreated first leaving behind sediment that created the middle part of the arm (the bicep). Next the easternmost lobe retreated and the sediment it left behind created the upper part of the arm (Provincetown). When the last glaciers melted about 18,000 years ago leaving behind an usual looking landform. Today, scientists know that the glaciers brought the sediment because they are all different colors, textures, and all have different layers.
A big problem in Cape Cod is beach erosion. The first reason why the beaches are eroding is because of rock jetties. Rock jetties that separate beaches interrupt the natural transfer of sand by the tides and wind. The…
