In geodesy, what is the conventional unit name for measuring gravity, known as the gal, related to the centimeter-gram-second system?

Explanation:
Gravity is an acceleration, and in the centimeter-gram-second (CGS) system the natural unit used to express it is the gal. One gal equals 1 centimeter per second squared, so measuring gravity directly in CGS yields values in gal. This unit is specifically for acceleration like gravity, which is why it’s preferred in geodesy. The other options correspond to different physical quantities: the Newton is a unit of force, the Pascal is a unit of pressure, and the Joule is a unit of energy.
