Definition : (Geo, G. the Earth; Morph, G. Form, ology G. the science of) Geomorphology is the study of landscapes--It entails the systematic description of landforms and the analysis of the processes that create them.
Nuclear binding energy is the energy that would be required to disassemble the nucleus of an atom into its component parts. These component parts are neutrons and protons, which are collectively called nucleons.
Thus, the mass of 0.030378 amu = 931 x 0.030378 = 28.3 MeV. The binding energy of a He atom is 28.3 MeV. The He atom is composed of 4 nucleons (2 protons + 2 neutrons), so the average binding energy per nucleon is 28.3 MeV/4 = 7.07 MeV. The average bindfing energy per nucleon varies for different atoms.
