How does the altitude of a place affect the value of 'g'?
The higher the altitude, the higher the 'g' value.
The higher the altitude, the lower the 'g' value.
The altitude of the site has no effect on the value of 'g'.
The effect of altitude on 'g' depends on the shape of the Earth.
The value of 'g' decreases as we move away from the center of the Earth. This means that as a location's altitude increases, so does its distance from the center of the Earth, resulting in a lower "g" value. However, the effect of altitude on "g" is relatively small compared to the effect of the shape of the Earth.
