Geophysical methods of subsurface investigation involve using techniques such as seismic surveys, ground-penetrating radar (GPR), electrical resistivity, and magnetometry to study the properties of the subsurface without invasive digging. These methods can help identify underground structures, geologic features, water tables, and potential hazards. Geophysical investigations are commonly used in construction, environmental assessments, and resource exploration.

What are the geophysical methods for soil exploration techniques?
Geophysical methods for soil exploration include techniques like electrical resistivity, ground-penetrating radar (GPR), seismic refraction, and electromagnetic surveys. These methods are used to investigate the subsurface characteristics of soil and rock layers, map the depth and extent of geological features, and identify anomalies associated with potential hazards or resources. Geophysical surveys can help in environmental studies, engineering projects, and natural resource exploration.
Use geophysical in a sentence?
Geophysical surveys are commonly used to map the subsurface characteristics of the Earth, such as locating underground water sources or identifying potential oil and gas reservoirs.
Which of the following scientists build subsurface descriptions of discovered oilfields?
Petroleum geologists typically build subsurface descriptions of discovered oilfields by analyzing data such as rock samples, well logs, seismic surveys, and other geophysical data. They use this information to create detailed models of the underground formations and structures that contain oil and gas reserves.
How is surface mining similar to subsurface mining?
Surface mining and subsurface mining are both methods used to extract minerals from the Earth's crust. However, surface mining involves removing the overlying rock and soil to access the mineral resources, while subsurface mining involves digging tunnels or shafts underground to access the mineral deposits. Both methods can have environmental impacts and require careful planning and management to minimize these impacts.
What are the surface and subsurface methods by which coal is commonly mined?
Surface mining methods for coal include strip mining, open-pit mining, and mountaintop removal. Subsurface mining methods involve underground mining techniques such as room and pillar mining, longwall mining, and shaft mining. Each method has its own advantages and challenges in extracting coal from the earth.
What Geophysical method for subsurface marble exploration?
Seismic reflection surveying is a commonly used geophysical method for subsurface marble exploration. By sending sound waves into the ground and recording their reflections, this method can help identify different rock layers, including marble, based on their acoustic properties. Other methods like ground-penetrating radar can also be used to locate marble deposits by detecting variations in subsurface materials.
What is an anomaly in geophysical exploration?
An anomaly in geophysical exploration is a deviation from the expected or normal data patterns. It can indicate the presence of subsurface features or conditions, such as ore deposits, faults, or changes in rock composition. Geophysicists use anomalies to identify potential targets for further investigation or to better understand the underlying geology of an area.

Principle of gravity geophysical exploration and it uses?
Gravity geophysical exploration is based on the principle that variations in subsurface density will affect the strength of the gravity field. By measuring these variations in gravity, geophysicists can create models of the subsurface, identifying locations of different geological features such as oil deposits, mineral deposits, and faults. It is widely used in mineral exploration, oil and gas exploration, and environmental studies.
What are 3 methods of investigation in science?

What is a G and G study in petroleum geology?
A G and G study in petroleum geology involves evaluating the subsurface structure and stratigraphy of a prospective area for hydrocarbon exploration. It stands for "geological and geophysical" study and combines geological mapping with geophysical data analysis to identify potential oil and gas reservoirs. This integrated approach helps in understanding the subsurface geology and is crucial for successful oil and gas exploration.
