Explanation:

As an object moves away from the earth and the atmosphere the weight of the object reduces but its mass remains constant because the gravitational pull decreases.Gravitational pull will also change subtly as you move around the surface of the Earth, varying with latitude and local topology, as the Earth is not a perfect sphere.
