Iron can be reduced from its ore by smelting (heating the ore). Known for over 2000 years.
Aluminium can only be reduced by electrolysis from its ore (Bauxite). Since electricity (electrolysis) was NOT available prior to 1850 AD, when electricity was 'unknown', then Aluminkium coul not be isolated.
No, because they were isolated, Native Americans did not know of the use of iron before the European colonization. People in Europe, Africa, and Asia found many uses for iron long before Native Americans.
400 billion years ago XD
I do not know about Norway, Denmark and Iceland but many lake-bottoms in Sweden are covered with Limonite, Iron-oxide, which is possible to harvest for Iron.
the iron age happened about 2.5 million years ago. the iron age was followed by the stone age, which happened about 3 million years ago
About 1200 years in Europe.
Iron was used for thousands of years before aluminum. While aluminum is more abundant, it is not as easy to work with as iron.
Because aluminum is an alloy which was discovered long after the iron age.
Because iron is always attracted to a magent, it will be pulled from the mixture. Aluminium will only be pulled by the magnet if certain conditions are met; as long as the metals aren't moving very quickly, a magnet has no effect on it and won't be pulled away.
Iron was used first because it was easier to aquire. In ancient times iron could be found either as the metal or as its ore and could be reduced to the metal by burning it with a high carbon source(charcoal was used until coke replaced it because of enviromental concerns and cost). Carbon is more reactive than iron so it reduces the ore to iron. While there is a lot of aluminium in the crust none of it is pure, and aluminium is more reactive than carbon so it was impossible to reduce with the normal methods of the ancients. Aluminium is produced by melting the ore and using electrolysis (this is sending an electric current through the liquid which breaks the molecular bonds. This requires electricity which the ancients were lacking in.). summary: iron was easier to get to and use P.S. it is good that they used iron for buildings and weapons. Aluminium fatiques and it would break, causing lots of problems.
yes, as long as it was cold before wrapped. It will also keep food warm to as long as it was heated before being wrapped as well. Just be sure to not put aluminum foil in the microwave!

Instantaneously. Elemental Aluminium metal reacts immediately with oxygen in the air, to form aluminium oxide. Aluminium oxide is a very stable compound, and so does not allow the underlying aluminum metal any further reaction. If you have aluminium pots and pans at home, then you are actually touching the aluminium oxide, because the underlying aluminium has already reacted with atmospheric oxygen .

Both aluminum and nonstick cookwares are safe for cooking use. However, aluminum can withstand more heat that nonstick cookware can. The non-stick part of a cookware will melt off at a certain temperature.
Cast iron, wrought iron and steel are all essentially alloys of iron and carbon.Wrought iron is iron with a low carbon content, it was used in place of Cast iron is iron that has been shaped by being poured into a cast.
Iron typically lasts for several years before it deteriorates or loses its effectiveness. The exact duration can vary depending on factors such as the quality of the iron, its usage, and environmental conditions.
