If the earth had a completely smooth surface and all the components form which it was made were all evenly mixed up, then the force of gravity would be the same at all points on its surface.
However the earth is not smooth , it has mountains and hollows in its surface and the rocks form which it is made are not evenly mixed, some surface rocks are heavy (dense) and some are light.
This means that as compared to the theoretical smooth earth gravity field, the real earth gravity field varies from point to point over the surface.
A gravity survey measures the small variations in the pull of gravity over the earth's surface and makes a map of these changes. This map helps geologists understand where the dense and light rocks are beneath the surface.
A gravity survey is a geophysical technique used to measure variations in the Earth's gravitational field. By measuring these variations, geoscientists can deduce the distribution of subsurface density variations, which can provide valuable information about the composition and structure of the Earth's interior. This method is commonly used in mineral exploration, geothermal exploration, and oil and gas exploration.

How do Geophysicists use gravity surveys?
Geophysicists use gravity surveys to map subsurface geological structures by measuring variations in gravitational pull caused by differences in rock density. This data helps in identifying underground features such as faults, mineral deposits, or oil reservoirs. Gravity surveys are commonly employed in oil and mineral exploration, as well as in environmental and engineering studies.

How is the gravity survey caried out today?
Gravity surveys are conducted today using highly sensitive instruments like gravimeters that measure the gravitational field of the Earth at different locations. These instruments are mounted on aircraft or vehicles to collect data across large areas quickly and accurately. The data is then processed to create maps showing variations in gravity, which can be used to understand subsurface geological features.
