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.
Iron has the largest binding energy per nucleon) generally releases energy (an exothermic process), while a fusion producing nuclei heavier than iron will result in energy retained by the resulting nucleons and the reaction is endothermic. The opposite is true for the reverse process, nuclear fission.
