December 26, 2004 , a major underwater earthquake occurred and caused a tsunami in Indonesia . The satellite pictures below show the coastline before and after the wave hit. Scientists hypothesize another earthquake is possible. If this occurs and another tsunami hits the same area, what changes could you predict happening to the coastline ?

The coastline could recede, which means that the height of the coast wouldn't be the same as before

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.
