A. Fossils of the same species were discovered in both Scotland and the
Appalachian Mountains,
B. The shape of western Africa is similar to the eastern coastline of South

C. Early sonar used in WWII found mid-ocean ridges,
D.. Many different species of dinosaurs were found in the western United
States,

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.

d. groundwater flows through the subsoil and deposits minerals.
