AGU provides information for the public on what is known about Earth, its planetary neighbors, and the space around them and how the geophysical sciences are advancing.

The four fundamental areas of the geophysical sciences are:

• Atmospheric and Ocean Sciences - climate change, hurricanes, tornados, tsunamis, air quality, sea ice, structure of the ocean bottom, biological processes.
  
• Solid Earth Sciences - earthquake prediction, structure and dynamics of the Earth's deep interior, volcanic activity, tectonic plates, mineral resources.
  
• Hydrologic Sciences - water supply and quality, waste disposal, groundwater contamination, droughts, floods, erosion.
  
• Space Sciences - solar storms, cosmic rays, space weather, magnetic fields, structure and evolution of planetary bodies.
