What do you mean by Geophysics?Explain various types of Geophysical Methods to measure properties of earth materials.

Geophysics is the branch of geological science which is the application of the concepts of Physics to study the interior of the earth.

There are various types of geophysical methods that measure respective physical properties of earth materials as explained below:

• Gravity Method

• Magnetic Method

• Electrical Method

• Seismic Method

• Geothermal Method

• Radiometric Method

Gravity Method:

This Method is used to measure the density of materials.

Magnetic Method:

This Method is used to measure magnetic susceptibility and natural remnant magnetism of materials.

Electrical Method:

This Method is used to measure electrical resistivity and conductivity of materials.

Seismic Method:

This Method is used to measure  elastic property i.e, seismic wave velocity of materials.
