How do sedimentary rocks form on the Hawaiian Islands?

I think they form on the Hawaiian islands because of the volcano.

Explanation: The heat may help them form,hope this helps.

specific gravity is the density of a substance divided by the density of water. since (at standard temperature and pressure) water has a density of 1 gram/cm3, and since all of the units cancel, specific gravity is usually very close to the same value as density

so "c" is the answer
