The cryosphere is the component of the Earth that composed of all solid, frozen water found on Earth. The cryosphere includes water storage areas such as glaciers, iceburgs, snow-covered areas, and sea ice. The cryosphere expands and contracts over the course of the months as average temperatures across the globe fluctuate.
The ionosphere is defined as the layer of the Earth's atmosphere that is ionized by solar and cosmic radiation. Short wave radiation that penetrates the Earth's atmosphere does not reach the surface.A few examples of short wave radiation are x-rays, ultraviolet and gamma rays. When these waves pass through the atmosphere, they ionize molecules of oxygen and nitrogen and create a thin ionized region known as the ionosphere.he ionosphere is very important because it can be used to help transmit radio waves across the globe. The radio waves are able to bounce off the ionosphere for communication purposes.
