3. when looking at hawaii, which side are the younger islands on? how do you know?

You could know if you go to the beach and you might see the island or you can climb to the top of dimond head like I did.  

(I live in Hawaii)

Hopes this helps

Please give me brainliest

Thank you,

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
