Geophysics is the physics of the Earth - The Earth, beneath our feet, but also the atmosphere, the oceans and the globe's thick icecaps. The solar system's earth-like planets also belong within the research area of Geophysics.

Geophysicists go on field work to remote places such as Antarctica or Greenland to bore ice-cores out of the kilometre thick icecaps, or sail round the world with the Galathea Expedition with measuring instruments to gather new knowledge about the condition of the global climate.

Climate Research in the past and the present and research into the solar systems earth-like planets such as Mars, Mercury,, the Earth and the moon also make up part of the geophyscical research area. This geophysical research often involves international collaborative projects, where many countries participate.
