Answer 1: oxygen and carbon in the air :-)
Answer 2: Depends on what type of corrosion you are referring to. Rust and corrosion are typically used interchangeably. Rust is one type of corrosion. Corrosion is essentially the disintegration of a engineered material. Rust is a chemical reaction, but there are other chemical reactions that cause corrosion of steel (typically acids).
Other types of corrosion include fretting, erosion, cavitation, and galvanic reactions.
There are many methods to prevent corrosion. One of the most versatile of prevention solutions is electroless nickel plating. Electroless nickel resists all types of corrosion.
Iron is the metal that causes the most concern for society regarding corrosion. It readily rusts when exposed to moisture and oxygen, leading to deterioration of structures and infrastructure. This corrosion can weaken the metal, compromising the safety and integrity of buildings, bridges, and other important structures.
A substance that causes pollution is called a pollutant. Pollutants can be in the form of chemicals, gases, or particles that are harmful to the environment and human health.
A contaminant is anything that lessens the quality of a substance or makes it harmful. A pollutant refers to something that contaminates the environment, specifically.
The main gases present in water that can cause corrosion are oxygen and carbon dioxide. These gases can react with metal surfaces, leading to the formation of corrosion products such as rust. Other gases, such as hydrogen sulfide, can also contribute to corrosion under certain conditions.
Iron combines with oxygen in the air through a process called oxidation, which results in the formation of iron oxide, commonly known as rust. Rust weakens iron structures over time, causing them to corrode and deteriorate.

Corrosion of metallic structures is predominantly caused by exposure to moisture and oxygen, which leads to the formation of rust. Crumbling of concrete and rocky structures can result from a combination of factors, including freeze-thaw cycles, chemical reactions, water infiltration, and poor construction quality. Over time, these elements weaken the integrity of the structures, causing them to deteriorate and eventually crumble.
