How terracing help prevent erosion?

I need to know how to prevent land erosion and you changed my question and I am very mad and i am going to use another website like google.I think that they will have an answer to this question.If I were you I wouldn't ask any more questions on here because they change your questions into completely different questions.I asked a question about how to prevent land erosion and it changed my question into:How to cook when your by yourself and you are hungry.Does that relate in any way to my question(except for using the Word "how")?I would not use this system to answer your questions if I were you.Hope you had a better time on this website than i did.Be careful.(That is not a threat.An if you watch American Idol, you know what I mean.)
