The acceleration due to gravity decreases with:

The acceleration due to gravity diminishes with increasing depth and height relative to the surface of the Earth. Moving toward the Earth core, only the mass beneath one’s location participates in producing gravity, reducing what is often known as the local gravity. Similar to moving out from the core, at elevated heights, because the distance from the earth’s center now increases, gravitation diminishes. In both scenarios, the acceleration due to gravity is reduced since it is proportional to the mass and distance of the body involved. Such differences are essential for determining gravitational changes across different regions on Earth or within the surrounding space.
