Why do metals corrode quickly near the sea?
Salt water is corrosive. And there is more moisture in the air.
Why metals corrode quickly near the sea?
There's more water vapor and other gases which cause corrosion.In water, they just go faster. -Neo
Why do metal corrode more quickly near the sea?

Why do metals corrode more quickly when near the sea?
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.
Iron and steel corrode more rapidly near the cost of an acean?
Salt is abrasive and we find salt in abundance in ocean so the salty water is carried towards the ,etals and thus they corrode more easily.
What metal corrodes with water?
All of them, to a greater or lesser degree, depending on their position in the "Electromotive Series of Metals," also known as the "Galvanic Series of Metals." This is a list of metals in order from most to least reactive in sea water. If there are two metals near each other in salt water, the one which is the more reacive (a.k.a. "least noble") will corrode, thus protecting the other metal. This is why ships often put chunks of zinc (called "zinc lozenges") near the propeller---without the zinc, the steel hull would corrode very quickly as it is more reactive than the bronze propeller. The zinc is more reactive than steel even, so it will do all the corroding and the hull is protected. Of course you have to replace your zinc lozenges periodically, as they will corrode away to nothingness eventually. Here is a simple one: From Most Noble (Protected Metals) to Least Noble (Corroded Metals): Mercury Vanadium Gold Silver Monel Nickel Passivated Stainless Steel (rare type) Copper Brass Tin Lead Active Stainless Steel (most common type) Cast Iron Steel Aluminum Zinc Magnesium You see that zinc is quite low on the list, and will corrode first and thus protect everything above it. Stainless steel is higher than ordinary steel---it stays stainless by forcing everything below it (like ordinary steel) to do the corroding. However, if you put stainless steel alongside nickel in salt water, the stainless will do the corroding and the nickel will be protected. Fancier lists include more metals and alloys of different metals.

What happens if you put algae near sunlight die stop growing turn yellow or grow more quickly?
Grow more quickly
Why should window frames not be made out of metal especially near the ocean?
Iron frames tend to corrode. The same is not true of all metals, and aluminium frames work quite well.
What metals rust more quickly near the sea?
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.
What are 3 main classes of elements and where are they located on the periodic table?
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.
Why comet travels more quickly on its orbit when it is closer the sun?
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
Do the metals naturally present in the human body attract magnets when they are near?
No
