There are nine planets in the solar system and each of those has different gravitational force or measurement. Earth, for many years is the only planet in the system to have and harbor life. This is the reason why human beings living on it must study every existing phenomena or scientific mystery in order to enlighten minds and answer questions exactly.

The problem here is that some scientists who are expert in studying about gravity have to thoroughly check the force from time to time. This can be why ground gravity survey is very important and must be paid attention. They are not just going to scientifically examine and get the results just like that but the results they get will be recorded in the history forever.

There might be some who question the importance of this kind of surveying and why there is really a must to do so. All the things that mankind encounter on a daily basis is practically connected to all the scientific mysteries in the planes which apparently need clarifications. If this matter is overlooked, then people are still not safe because they are still not aware of what things it can do.

For those who do not know, this kind of survey is a non invasive and low impact geophysical technique. Many people know that the gravity of the Earth is 9.8 however, that is not always like that. There are some parts of the planet where an object is heavier and there would be some that the object is lighter and this is why it is significant to study such thing.

These experts would use a modern device known as gravimeter that would measure force under top soils. This is the thing that is usually used in exploration. Unlike other measuring devices, this thing may not be that convenient but it could somehow be brought in a larger bag pack. For it to work, it is put on a particular ground and it would just take several minutes to obtain the results and then later put at a different location to compare.

In surveying, the site where the machine is put must have a silent environment and miles away from machines that cause land disturbance nearby. These machines could be land autos or heavy trucks, helicopter or ships. As mentioned again, the device is not invasive like others so it will not cause any disturbance or tampering with gravitational force when used.

Just like any other measuring devices, this gravitational instrument to type and they are absolute and relative. The absolute ones are accurate tools applied to monitor subsidence surveys. The ones that are commonly used are the relative gravimeters for geophysical exploration applications. Without this classification, the work will not be that easy.

The concept of this survey is to anticipate the depth of investigations, contrast, density, and its geological structure. This means that they need to study every layer of the ground to get accurate and precise results that will eventually help them in their goals. In doing this, measurements should be taken in closed loops.

There is a sack of phenomena in the planet in which many individuals have no knowledge but as long as there are genius professionals, they will do their best to provide people the answers to their questions. People must not also blame the scientists for their mistakes because their work is as hard as a rock. A person must always take note of this.
