Detailed explanation-1: -When iron is exposed to moist air it reacts with the oxygen present in the air to form ferrous oxide. This is a brown flaky layer coating formed on iron and causes the destruction of iron. This formation is known as rust, and the process is known as rusting.
Detailed explanation-2: -Iron when reacts with moist air forms a reddish brown layer of iron oxide which is known as rust.
Detailed explanation-3: -Red rust is the result of heavy exposure to air and moisture, combined many times with a contaminate (salt). This type of rust is most likely atmospheric because typically there are no signs of rust runs or streaks on the metal parts/equipment where the rust has formed.
Detailed explanation-4: -Rust is iron oxide, which forms when iron or an alloy that contains iron is exposed to oxygen and moisture for a long time. The resulting reddish-brown appearance is due to hydrated iron(III) oxide formation. Rusting is an electrochemical process that begins with transferring electrons from the metal to oxygen.
Detailed explanation-5: -Therefore, the reddish brown substance formed on iron is called rust.
