USES OF GRAVITY FOR EARTH STUDIES

- MEASURE AVERAGE DENSITY OF PLANET AND DRAW INFERENCES ABOUT ITS COMPOSITION

 

- USE GRAVITY VARIATIONS TO MAP BATHYMETRY

(SEA FLOOR TOPOGRAPHY)

 

- IDENTIFY LOCAL DENSITY VARIATIONS DUE TO GEOLOGICAL STRUCTURES (MOUNTAINS, MID-OCEAN RIDGES, ETC.) AND USE THE VARIATIONS TO STUDY THE PROCESSES THAT CAUSE THEM
