Who specializes in exploring the subsurface with magnetic gravity or seismic surveys?
Geophysicists specialize in exploring the subsurface using magnetic, gravity, and seismic surveys. They use these techniques to detect variations in the Earth's subsurface properties, such as rock density, composition, and structure, to help locate Natural Resources like oil, gas, and minerals.

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.
Why do people have different weight on different planets or on the moon?
Because different planets have different mass, which means that gravity is weaker or stronger depending on the mass. If gravity is stronger than objects will have more weight, and if it's weaker they will have less weight.
Why do researchers need gravity surveys?
Researchers use gravity surveys to study the density variations beneath the Earth's surface. By measuring slight changes in gravitational pull, they can map out geological structures, identify potential mineral deposits, and understand tectonic processes like plate movements. This information is crucial for various fields such as geology, geophysics, and natural resource exploration.
What is true about an objects weight but not about its mass?
An objects weight is the amount of the pull of gravity on an object. On the other hand, mass is the amount of matter in an object. You`re mass is the same on every planet. For example, lets say on earth you weighed 100 pounds. On Venus you would weigh the same. BUT, you`re weight is different on different planets. For example, on the moon, the amount of the pull of gravity on you would be different in a way that you would be 70% lighter. Hope that helps. Adios! And no, I am NOT Spanish.(False) It would be the same on the moon as it is on Earth.
Why do objects have weight?
Objects have weight due to the force of gravity acting upon them. The weight of an object is a measure of the gravitational force pulling it towards the center of the Earth. The greater the mass of an object, the stronger the gravitational force and the heavier the object will be.
Does mars have a gravity magnetic field?
Mars has gravity, as do all planets, but not a magnetic field.
Is gravity and magnetic forces the same?
No, gravity and magnetic forces are not the same. Gravity is a force of attraction between objects with mass, while magnetic forces are due to the presence of moving electric charges. Gravity acts on all objects with mass, while magnetic forces act on objects with electric charge.
Is a force that acts at a distance?
The electric force, the magnetic force and gravity, all act at a distance.The electric force, the magnetic force and gravity, all act at a distance.The electric force, the magnetic force and gravity, all act at a distance.The electric force, the magnetic force and gravity, all act at a distance.
Does earth's magnetic field cause gravity?
No, Earth's magnetic field and gravity are two separate phenomena. Earth's magnetic field is generated by its core while gravity is a fundamental force that exists between all objects with mass. Gravity is responsible for the attraction between objects, including the force that keeps us anchored to the Earth.
What does positive gravity indicate in geology?
Positive gravity anomalies in geology indicate areas where the density of subsurface material is higher than average. This can be caused by denser rock types, such as iron-rich minerals, or by the presence of denser materials like metallic ores or large underground structures. Positive gravity anomalies can be useful for identifying potential mineral deposits or mapping subsurface geological structures.
Which method uses the density differences of rocks to interpret subsurface structures?
Seismic reflection is the method that uses the density differences of rocks to interpret subsurface structures. It involves sending seismic waves into the ground and measuring the reflections to create a picture of the subsurface geology based on the different densities of rock layers.
Is groundwater powered by gravity?
Groundwater is primarily replenished by precipitation infiltrating into the ground. Gravity does play a role in how groundwater moves through the subsurface, as it causes the water to flow downward due to the force of gravity, but it is not the primary power source for groundwater.
Is gravity responsible for rotation of a planet?
That and the magnetic force
Why is gravity caused by earths magnetic field?
It isnt. Two different forces; gravity and magnetism. As for how gravity works; all objects have their own "gravity", the bigger they are, the more gravitational pull they have. Why gravity works; nobody knows or we would all have flying cars.
What is bouguer correction?
Bouguer correction is a method used in geophysics to account for the gravitational attraction of material between the measuring point and the center of the Earth. It is applied to gravity measurements to remove the effects of terrain and topography, allowing for a clearer interpretation of subsurface geology or mineral deposits. Bouguer correction helps to isolate the gravity anomalies caused by subsurface features.
Why are magnets able to overcome force of gravity?
You don't specifically need a magnet to overcome the force of gravity; ANY force that is stronger than gravity can "overcome" it, at least temporarily. For example, if you lift an object up, you are "overcoming" the force of gravity.
