How are islands formed?

There are two types of islands. Continental and Oceanic.

Wiki is perfectly fine for stuff like this. I am constantly checking its accuracy in the sciences.

boy I must've missed something. I used to go fishing off an island in little sebago lake, where there hasn't been any volcanic activity in about 600 million years.
Either this question is extremely vague or there are so many ways of forming islands that describing them would take pages on pages.
How do the given answers explain the Florida Keys or Long Island New York? The island where fort sumter was built. Alcatraz Island? Island number 10 (or whatever) in the mississipi river? I think you get the point.

Some islands like hawaii are formed by volcanoes exploding. The ash cools down and forms into land
Another way, as seen in ancient geography maps, is that as the land slowly moves ( plates) move slowly about a few centimeters a year.
Hope this helped u âº

1{001_cN_math_Ãot has no idea what he's talking about. surtseyan volcanic eruptions can eventually form islands, but its pretty rare.
Islands are generally formed by hotspots on a plate. this can be oceanic or continental (Geomatic7000 has the idea.. except wiki isn't the most reliable source ;) )
