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).
What Is The Cryosphere? The cryosphere is the frozen part of Earthâs surface. This includes glaciers, snow, sea ice, freshwater ice, permafrost, ice caps, and ice sheets. The cryosphere plays a significant role in the global climate by influencing hydrology, clouds, precipitation, and circulation of the atmosphere and the oceans. The term cryology refers to the science of cryospheres and deglaciation is the loss of the cryosphere (such as the reduction of global ice content due to global warming).
