WebThis visualization of a gravity model was created with data from NASA's Gravity Recovery and Climate Experiment (GRACE) and shows variations in Earth’s gravity field. Gravity is determined by mass. Earth’s mass is not distributed equally, and it also changes over time. The colors in this image represent the gravity anomalies measured by GRACE.
