It is a form of soil degradation. This natural process is caused by the dynamic activity of erosive agents, that is, water, ice (glaciers), snow, air (wind), plants, and animals (including humans ). In accordance with these agents, erosion is sometimes divided into water エロージョン（erosion）は「浸食」でコロージョン(corrosion)は「腐食」ですが、実際の不具合現象では、組み合わせで起こる場合も有ります。 エロージョンとは？ キャビテーションエロージョン（cavitation erosion）は、流体中での流速や圧力変化により局部的に飽和蒸気圧以下の圧力となることに Rsearchers: Mega iceberg shows signs of erosion. Last month, EYOS Expeditions arrived at iceberg A23a and used a drone to capture video and found significant erosion and transformation, expedition Soil erosion decreases soil fertility, which can negatively affect crop yields. It also sends soil-laden water downstream, which can create heavy layers of sediment that prevent streams and rivers from flowing smoothly and can eventually lead to flooding. Once soil erosion occurs, it is more likely to happen again. This is a global problem. The FCWD is comprised of nine local governments that manage the the creek's 927 square miles from Palmer Lake to Pueblo.
