Because some metals are reactive and corrode in sea water
Salt water is corrosive. And there is more moisture in the air.
There's more water vapor and other gases which cause corrosion.In water, they just go faster. -Neo
Grow more quickly
Salt water is corrosive. And there is more moisture in the air.
The salt in the sea air oxidizes the metals Very similar to the way salt used on roadways in the northern states during winter causes corrosion on cars.
Rust in it's truest definition is Iron(III) Oxide, meaning the only metal that can "rust" is Iron. If you are asking, "What metals oxidize more quickly near the sea?" The answer would still be Iron or steel, which has Iron in it. Oxidation occurs when metals have chemical reactions with Oxygen in the air and water. Rust occurs when the Iron atoms lose a few electrons to the Oxygen atoms and deteriorates the structure of the molecules, creating weak points. Salt water and salty air allows ions to flow more easily from objects creating faster decay. Ships battle this natural process be attaching galvanic anodes to the hull of the ships, this anode can be made out of Magnesium, Aluminum, or Zinc and basically creates a magnet for the ions, from the Oxygen, to "attack" it instead of deteriorating the Iron. These anodes need replaced about every 6 months.
Non-metals, metals and semiconductors. Metals are on the left, non-metals on the right, and semiconductors sitting near the staircase line that divides the metals and non-metals.
the comet moves fastest near the sun because the gravitational movement pulls it quickly and gets rid of the rock and ice on the tail
No
Most (if not all) metals are good conductors of heat and electricity, and most (if not all) metals are shiny. Copper, iron, sodium, calcium and a lot more are possible answers to your question.
Near the sea exposed metals have a greater exposure to salts, which accelerate the rusting process.
