Earth’s Gravity Field

Earth’s gravity field is the invisible force that pulls objects toward the planet's center. It varies slightly across different locations due to factors like surface features, density variations inside Earth, and mass distribution. This field is responsible for keeping everything anchored on the surface and governs the motion of satellites and celestial bodies. Scientists study Earth's gravity field to better understand its internal structure, monitor changes like melting ice or shifting mass, and improve navigation, oceanography, and understanding of Earth's geophysical processes. Essentially, it’s the gravitational influence Earth exerts on objects and its environment.
