Polar cusps-Two funnel-shaped areas between the Sunward magnetic field and the tailward magnetic field where the solar wind enters and follows the magnetic field lines toward Earth.
Magnetosheath-The region between the bow shock and the magnetopause, characterized by very turbulent plasma.
Plasma mantle-the region covering the magnetosphere that extends toward the cusp region that contains de-energized magnetosheath plasma
Plasmasphere-A region of cold, dense plasma inside the magnetosphere that is populated by the outflow of ionospheric plasma along the magnetic field lines.
Van Allen belts-Two ring-shaped regions that girdle the Earth's equator in which electrically charged particles are trapped by the Earth's magnetic field
Plasma sheet-a layer of weaker magnetic field and denser plasma that is centered on the equator and seperates the two tail lobes.
Boundary layer-The lowest layer of the Earth's atmosphere where the wind is influenced by the friction of the Earth's surface and the objects on it.
Magnetopause-The boundary surface between the solar wind and the magnetosphere where the pressure of the magnetic field equals the pressure of the solar wind
Shock front (bow shock)-A collisionless shock wave in front of a planetary magnetosphere; the place where the supersonic flow of the solar wind is slowed to subsonic speed by the planetary magnetic field
Magnetotail- The portion of a planetary magnetosphere which is pushed in the direction of the solar wind
