In my experience burning out alternators on a Pontiac and an Oldsmobile, you can get about 100,000 miles out of it before expecting to replace the alternator.
Impossible to answer as it depends on use and abuse. Normal use will see no need to replace one on a modern car.
I have a 2003 Yukon with 211,000 miles, the only thing I have reoplaced is the battery and the alternator.
Spark Plugs do not affect your alternator. As long as your engine is running then it should be charging unless your alternator is bad
It should take around about an hour, varies on if you have anything ready.
Antarctica should last as long as the earth lasts.
Should last about 30 minutez
It should last five to six minutes.
Either the life of the vehicle, or 100,000 - 200,000 miles. However mine has gone at 3,000, which is why I am embroiled in a dispute over the £400 cost from a Ford Main Stealer!
A properly configured sealed terrarium should last indefinitely.
