Geophysically → It is formed from "geo-" (from Greek "gē", meaning earth) and "physical" (from Greek "physikos", meaning natural or pertaining to nature) and the suffix "-ly" (meaning in a manner). The word "geophysically" refers to something that relates to the physical properties and processes of the Earth.
Think of 'geo-' meaning 'earth' and 'physical' relating to 'nature' — so geophysically means in a manner that pertains to the natural properties of the Earth.
