The Chromosphere. Click on image for larger version. The chromosphere is an irregular layer above the photosphere where the temperature rises from 6000&degC to about 20,000&degC. At these higher temperatures hydrogen emits light that gives off a reddish color (H-alpha emission).
The magnetosphere is the region of space surrounding Earth where the dominant magnetic field is the magnetic field of Earth, rather than the magnetic field of interplanetary space. The magnetosphere is formed by the interaction of the solar wind with Earthâs magnetic field. This figure illustrates the shape and size of Earthâs magnetic field that is continually changing as it is buffeted by the solar wind.
