From Conservapedia
Geophysics is the branch of the Earth sciences which is studies the physical pehenomena which are relevant to the structure, physical conditions and evolutionary history of the Earth as a whole.
Topics of interest include:
- Seismology - the study of earthquakes and the shock waves that they produce
- Gravity - the gravity field and rotation of the earth
- Magnetics - the magnetic field of the earth and how it varies in strength and orientation
- Temperature gradients and heat flow
- Electromagnetic effects
- Natural radioactivity
- Oceanography - the physical aspects of the world's seas and oceans
- Meteorology
Many of the techniques used in geophysics have commercial applications in geophysical prospecting for oil & gas, minerals and water.
Near-surface techniques have applications in archaeology and ennvironmental studies.
