WebSep 5, 2024 · Read 4 answers by scientists to the question asked by Ali Sam on Nov 7, 2015 WebTopographic corrections have three parts which account for rock density changes, elevation, and the non-homogeneous effect of terrain. The first of these corrections is the free-air correction which adjusts for changes in elevation. For every meter of height change, the observed value of g decreases by 0.3086 mGal.
