Answer is Ionosphere. The ionosphere is a layer of ionized air in the atmosphere extending from almost 80 km above the Earth's surface altitudes of 600 km and more. Technically, the ionosphere is not another atmospheric layer. [ It occupies the same region of the upper atmosphere as the thermosphere. In this region of the atmosphere the Sun's energy is so strong that it breaks apart molecules. and atoms of air, leaving ions (atoms with missing electrons) and free-floating electrons. The ionosphere is the region of the atmosphere where the aurorae occur.
The ozone layer is the layer of the atmosphere that filters the  sun's rays. This layer is located in the upper atmosphere called  the stratosphere.here is no layer in the sun that filters out dangerous rays, but the layer in the earth that filters out said rays is called the ozone layer, also known as the startosphere. â¦ It consists of O3 molecules that break apart under the impact of rays and then re-form to re-create the barrier again.
