Rust on metal is an oxide of that metal. Most commonly it refers to iron oxide.
Rust on a plant is a disease caused by a pathogenic fungus.
In English the same word is used for these two very different things, possibly because the fungus on a leaf looks something like rust on iron. Many other languages use completely unrelated words for the two things.
Think this through. What is the difference between sea water and freshwater? Salt. What does salt do? Rust or create buildups on metal. What types of metal? Several types including iron and steel.
Iron or steel will rust, this is called oxidation. It's a reaction between oxygen and iron or steel
Rust forming on a metal gate is a chemical change. It is a result of a chemical reaction between iron, oxygen, and water, which leads to the formation of iron oxide (rust).
Oranges and other acidic fruit like lemon have acids in them that will rust the metal
Iron is the only metal that can rust. The usual term for the destruction of a metal by oxidation is corrosion, and 'rust' or 'rusting' is the term for corrosion specific to iron and its compounds.
Metal rust will not harm trees. There are a number of fungus rusts that can harm plants but they are not metal rusts.
Something that is rust resistant will not rust easily; minor exposure to water will not cause it to rust. Something that is rust proof will not rust.
poephol!!! poephol!!!
No light evaporates the water rusting the metal, not a lot but enough to make a significant difference.
The more saltwter will make it rust faster.
Aerosol does not make metal rust, rust is actually another element in the air effecting the metal.
Gold is not the only metal that does not rust. Copper is another metal that doesn't rust, and so is platinum and nickel.

rust is the answer
Iron or steel will rust, this is called oxidation. It's a reaction between oxygen and iron or steel
No, rust is the formation of a layer of a metal oxide on the surface of a metal.
Rust flakes away from metal because its a layer of loose material. The metal underneath is no longer protected and will begin to rust also.
