Which boundary has the greatest density change? Moho
Liquid Solid
no way to know
O Glutenburg

Glutenburg

Explanation:

The earth subsurface is composed of distinct layers stacked on top of one another. The Layers are named and usually subjected to high temperature and pressure as the depth increases. The layers distinctly include ; the crust, the mantle and the core. The Glutenburg boundary exists between the mantle and the outer core . Hence, it exists at greater depth, hence higher density than the mohorovicic boundary which separates the mantle and the crust. The moho exists at a depth of about 35 km compared to Glutenburg which occurs at a far greater depth of over 2500km beneath the continental crust.

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.
