Aseamount is a submarine volcanic mountain. would you expect older volcanoes to be seamounts or islands. explain your answer.

I would expect them to be islands. As a volcano grows older the magma it releases would accumulate and solidify until the volcano was no longer below the water level. The longer a volcano is active the less likely it is to remain underwater due to this gradual build up.

The one that most represents the earths mantle would be the skin since the mantle is the upper part of the earths depths which is just like the skin of an apple.
