Which technique is used for the exploration of deep-seated mineral deposits?

Aerial Surveys
Satellite Imagery
Geophysical Surveys
Ground-penetrating Radar

The correct answer is C. Geophysical Surveys.

Geophysical surveys are used to explore the subsurface of the Earth for a variety of purposes, including the exploration of deep-seated mineral deposits. Geophysical surveys use a variety of methods to detect and measure physical properties of the Earth’s subsurface, such as gravity, magnetic field, electrical resistivity, and seismic waves. These measurements can be used to identify anomalies that may be indicative of mineral deposits.

Aerial surveys and satellite imagery are used to map the surface of the Earth. These methods can be used to identify areas that may be prospective for mineral deposits, but they cannot be used to directly detect mineral deposits. Ground-penetrating radar is a geophysical method that can be used to detect buried objects, but it is not typically used for the exploration of deep-seated mineral deposits.

Here is a brief explanation of each option:

  • Aerial Surveys: Aerial surveys are used to map the surface of the Earth from an aircraft. This can be used to identify areas that may be prospective for mineral deposits, such as areas with exposed rocks or vegetation that is indicative of mineralization. However, aerial surveys cannot be used to directly detect mineral deposits.
  • Satellite Imagery: Satellite imagery is similar to aerial surveys, but it is used to map the surface of the Earth from a satellite. Satellite imagery can be used to identify areas that may be prospective for mineral deposits, but it cannot be used to directly detect mineral deposits.
  • Ground-penetrating Radar: Ground-penetrating radar is a geophysical method that uses radar waves to detect buried objects. Ground-penetrating radar can be used to detect buried pipes, cables, and other objects, but it is not typically used for the exploration of deep-seated mineral deposits.
