侵蚀：
侵蚀作用或水土流失是自然界的一种现象，是自然环境恶化的重要原因。由于水的流动，带走了地球表面的土壤，使得土地变得贫瘠，岩石裸露，植被破坏，生态恶化。侵蚀作用可分为风化、溶解、磨蚀、浪蚀、腐蚀和搬运作用。
水土流失可能是由于自然环境引起的，譬如地势陡峭，突发大量降水，或者地质变化。但更多的是由于人类活动导致的，譬如过渡放牧，开垦土地，采伐森林等等。
这种自然现象可以是循环作用的，生态恶化引起水土流失，水土流失又使得生态更加恶化。于是土地退化，无法耕种。植物死亡，地表裸露。恶劣的生态又更导致气候的变化，使得整个人类生存的环境变坏。
水土流失还会使得泥沙淤积，河床抬高，引起水流不畅，水质混浊，甚至导致洪水泛滥，河流改道，就如中国的黄河。
侵蚀作用也可能是正面的,如河流将碎石带入下游.
