Summary Introduction

To explain:

The reason that iron pipes typically corrode more quickly when they are buried in moist anaerobic soil than when they are buried in soil containing oxygen.

Introduction:

Iron oxide also is known as rust form when the iron is exposed to an environment containing oxygen, particularly in the presence of water or air moisture. Given proper time along with water, and oxygen, iron masses convert into rust and disintegrate completely which provide no protection to the underlying iron.
