Igneous rock from volcanoes;they float if you put in water due to the trapped air that was there while it cooled and hardened.(pumice,basalt)
Sedimentary rock from the oral reefs breaking up and forming condensed layers of sandstone and limestone.They are fine grained and light in weight.
Metamorphic rocks fom the island and mountain building areas are heavy and coarse grained rock like marble.

The entire Hawaiian island chain is made of basalt. Nearly every rock you find is basalt.
