What is GeoPhysics

What is Geophysics

The term geophysics refers to 
Earth's shape;

 its gravitational and magnetic fields; 

its internal structure and composition; 

its dynamics and their surface expression in plate tectonics,

the generation of magmas, volcanism and rock formation.

However, modern geophysics organizations and pure scientists use a broader definition that includes the water cycle including snow and ice;

fluid dynamics of the oceans and the atmosphere; 
electricity and magnetism in the ionosphere and magnetosphere and solar-terrestrial relations; 
and analogous problems associated with the Moon and other planets.
