  • The earth is spinning - so centrifugal force at the equator counteracts gravity and makes it seem like gravity is less at the equator than at the poles. Strictly, this isn’t “reducing gravity” - the gravitational force didn’t change - it’s just being counteracted by centrifugal force. BUT because of the reduction in “gravity” the earth bulges a little bit around the equator - and that means that on the equator you are further from the center of the earth and gravity truly is less because of that. So you weigh less at the equator as the result of TWO interrelated effects.

Nearby mountains can also bend the gravitational force slightly sideways so that “Up” isn’t truly “Up”
