Earth's non-uniform topography, like mountain ranges and ocean trenches, causes variations in gravity known as anomalies. Mountains create positive anomalies, indicating stronger gravity, while ocean trenches and glacial land create negative anomalies. NASA's GRACE mission maps these variations, offering valuable insight into Earth's gravitational field. 
It's amazing how Earth's features like mountains and trenches affect gravity. Positive and negative anomalies sound so intriguing. NASA's GRACE mission must be uncovering some incredible insights into our planet's gravitational field.
