SIR ISAAC NEWTON (1642-1727)
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
