The deep water has less oxygen in it than shallower water, therefore there is less rust and corrosion. The colder, deeper water is also more dense (more pressure on it from the weight of the water above it) and the chemical combination is therefore slightly different. But I am not an oceanographer or marine scientist.

∙ 14y agoRusting is oxidation of iron, and oxidation requires (you guessed it) oxygen. In shallow water, surface agitation of sea water means that oxygen is constantly being redissolved into the sea water. In deep water, there is a greater scarcity of oxygen, and so rusting takes longer.

∙ 10y agoSimple Answer:
Traditional iron oxidation known as "rust" does not occur rapidly in deep oceans because there is little oxygen present. In such oxygen deprived environments, more complex chemical and biological processes ultimately accomplish the process of corrosion and degradation.
More information:
The usual process of iron rusting is oxidation and requires iron and oxygen.
Only the top kilometer or less of the ocean has much dissolved oxygen.
The process of corrosion in the deep ocean is predominately through biological activity, particularly anaerobic bacteria. (The relationship between oxygen and depth is more complicated because there can be more oxygen at the very greatest depth as a result of processes that create deep ocean currents.) In addition to the cold and oxygen deprived nature of the water, objects on the ocean floor may be embedded in layer of material that further isolates it from the oxygen environment.
The wreck of the Titanic is an example of the complex deterioration process. Located at a depth of almost 4 kilometers, there is some rust but the main process causing iron decay is the action of anaerobic iron eating bacteria that reduce dissolved sulfates to form hydrogen sulfide which in turn corrodes the iron producing iron sulfide. The process has gone on for a hundred years and it is estimated that it will take about another hundred years for the Titanic to structurally destroyed. (See related links.)

I don't know whether the main question is why iron rustsor why does it rust slowly but i will answer bothiron rusts in air because air contains oxygen and water.and for rusting to occur, you NEED both oxygen and water..why it rusts slowly because , although air has an abundance of oxygen (~30%) water does not (~1%) and that is why it rusts slowly. because there is lesser water in the air to react with the iron and oxygen.
I don't believe; an iron nail is rusted in lemon juice and ocean water.
It caused iron in ocean water and terrestrial rocks to rust (oxidize).
The salt (the ion chloride) in the ocean causes corrosion which rusts metals or any other substances.
Iron corrodes to form an iron oxide. This oxide is commonly called rust. The reaction involves a transfer of electrons from iron to oxygen. Water is commonly slightly acidic due to the carbon dioxide in the atmosphere. The acid brings hydrogen ions in contact with the iron which allows the formation of an iron hydroxide intermediary compound which hastens the formation of iron oxide, rust. Ships at the bottom of the ocean rust more slowly as there is less oxygen and the water is less acidic. The only way to prevent rust forming is to prevent oxygen coming in contact with the iron through the application of paint, oil, plastic or another metal.
Rusting is the result of oxidation of iron (steel). Theer's more dissolved oxygen in shallow water than there is in deep water.
Yes, Slowly after time :)
Yes, Windex will cause rust slowly after time. If in a container it will turn a dark green color.
Iron will slowly rust in cold water.
Some cars rust faster than others. It depends on the technology used in the making of the cars. There are old cars who rust very slowly and new cars who rust very quickly.
There are a lot of factors.. rusting is the oxidization of iron, it needs the water and air. Most tools are Chrome plated (or similar) which will protect the iron from the air - so rust will occur where there is a scratch or wear - and then the rust may form a layer that protect the rest of the tool from further rust. The amount of air in the water and the movement of the water will also effect how quickly rusting occurs. There have been plenty of old tools found on shipwrecks that are still in "reasonable" condition - covered in rust but still recognisable
Chromed items can certainly rust, it depends on the quality of the chrome job, the maintenance of the item, and the conditions the item is stored and used in. Dry = little risk of rust, wet= bigger risk of rust. wet and salty, as when close to the ocean = big risk of rust.

Surface rust on a truck frame can be removed with abrasives like sand blasting or a scale removal tool. If the rust is deep then it may have compromised the frames integrity and will need to be professionally cut out and replaced.

They will have flash rust due to moisture, if they are thick enough, driving slowly, after a few miles of light braking will clean them of the rust.
No it is currently being eaten away by a harmful rust bacteria
